摘要： An impulse radar that forms a predetermined radar pulse train in space by transmitting individual spectral components thereof. Thus, a train of extremely short pulses is obtained without switching a radio frequency signal on and off at a high rate. An oscillator is coupled to a harmonic generator, and a power divider distributes the output of the harmonic generator to a multiplicity of amplifiers. Each amplifier has a phase-locked VCO circuit that provides frequency accuracy, spectral purity, low noise and frequency stability. Thus, each amplifier provides one of the spectral components of the predetermined radar pulse train. The amplifiers are coupled to a multiplexing feed that illuminates a reflector. On receive, the multiplexing feed separates the spectral components of the incoming pulse train. Each spectral component is coupled to its own narrow band receiver, and one receiver is used to amplify and detect each spectral component. The signals from the receivers are coherently combined in a signal processor in which the signals add coherently and the noise signals do not. The output of the signal processor may be applied to a radar display. The short pulses produced by the radar provide very high resolution, and can map a target by sweeping across it, thus imaging it. The radar emits a wideband signal at a low power level; the signal is difficult to detect and intercept, and thus provides for a low probability of intercept radar. The radar may be used as a microwave link, wherein the oscillator may be frequency modulated to provide communications. It may also be used as a covert IFF system to identify friendly aircraft. The radar provides signals that penetrate sand and may be used for mapping and to locate land mines buried in the sand. It may also be used for clearing away land mines by detonating them. When the power is turned up, the radar provides for a directed energy beam. The radar may perform adaptive jamming, and is also a jam resistant radar. It is hard to jam because the receiver array is insensitive to noise at frequencies outside the narrow bandwidths of the individual receivers and also to noise which is not coherent across the multiplicity of receiver channels.

摘要： A predetermined radar pulse train is formed in space by transmitting individual spectral components thereof. Thus, a train of extremely short pulses is obtained without switching a radio frequency signal on and off at a high rate. A crystal oscillator is coupled to a harmonic generator such as a comb generator. A power divider distributes the output of the harmonic generator to a multiplicity of final filter amplifiers. Each final filter amplifier has a phase-locked VCO circuit that provides frequency accuracy, spectral purity, low noise and frequency stability. Thus, each final filter amplifier provides one of the spectral components of the predetermined radar pulse train. The final filter amplifiers are coupled by duplexers to a broadband multiplexing feed such as a nested cup dipole feed that illuminates a reflector. On receive, the broadband multiplexing feed separates all the spectral components of the incoming pulse train. Each spectral component is coupled to its own narrow band receiver by the duplexers. One receiver is used to amplify and detect each spectral component. The signals from the receivers are coherently combined in a signal processor in which the signals add coherently and the noise signals do not. This provides a processing gain in signal to noise ratio corresponding to the total number of receivers. The output of the signal processor is applied to a radar display.

摘要： A rotating wing aircraft has a rotating fuselage and wings. The aircraft is configured to rotate with the air passing over the wings because of the rotation providing the lift needed to keep the aircraft aloft. The wings have rudders coupled to them, such as at the tips of the wings, to provide force for laterally moving the aircraft. The aircraft may be able to remain airborne by hovering for a long period of time, on the order of days. Power for the aircraft may be provided by a central diesel electric generator, which provides power for electric motors that turn propellers that are on the wings. The aircraft may be used for any of a variety of applications, such as for surveillance, communications, or as a radar platform.

摘要： A spark discharge focused drill provided with one pulse forming line or a number of pulse forming lines. The pulse forming line is connected to an array of electrodes which would form a spark array. One of the electrodes of each of the array is connected to the high voltage side of the pulse forming line and the other electrodes are at ground potential. When discharged in a liquid, these electrodes produce intense focused shock waves that can pulverize or fracture rock. By delaying the firing of each group of electrodes, the drill can be steered within the earth. Power can be fed to the pulse forming line either downhole or from the surface area. A high voltage source, such as a Marx generator, is suitable for pulse charging the lines.

摘要： A system and method is described for obtaining a spatial characterization of a particle beam, including the beam direction, position, divergence, aberrations and intensity profile. A mechanism is also provided for adjusting the beam propagation to a desired state in response to the sensed characteristics. A fiber array in the path of a neutral particle beam casts shadows which are sensed at a downstream location to characterize the beam. Various mechanisms can be used to sense the shadow positions and/or widths relative to the fibers, from which the various beam characteristics can be derived. By magnetically removing charged particles from the neutral beam shadows, the shadows can be sensed by their effect upon the secondary emission currents generated in downstream conducting sensor wires, by their effect upon the fluorescence of downstream optical fibers, or by their effect upon the thermal heating of various types of downstream heat sensors. The shadows can also be sensed directly by the differences in their spectral radiation compared to that of the beam. A very high degree of precision is obtained in directing the beam, while initial coarse measurements and adjustments can be derived by providing the fiber array as a grid of conductive wires and sensing differentials in the secondary emission currents generated in the various wires.

摘要： A particle mass spectrometer includes a supersonic flow expansion nozzle, and a source of a gas having particles entrained therein. The source is in gas-flow communication with an inlet of the expansion nozzle. The particle mass spectrometer further includes a vacuum chamber in gas-flow communication with an outlet of the expansion nozzle, wherein the vacuum chamber has a sufficient vacuum that a gas flow through the expansion nozzle is supersonic, and a microphone having an active element and an output signal responsive to a movement of the active element. The active element is disposed within the vacuum chamber and is positioned so that particles that flow from the outlet of the expansion nozzle impact upon the active element. The output signal of the active element of the microphone is a measure of the masses of the entrained particles.

摘要： An electromagnetic radiation source is provided which includes an anode and a cathode separated by an anode-cathode space. The source further includes electrical contacts for applying a dc voltage between the anode and the cathode and establishing an electric field across the anode-cathode space. At least one magnet is arranged to provide a dc magnetic field within the anode-cathode space generally normal to the electric field. A plurality of openings are formed along a surface of the anode which defines the anode-cathode space, whereby electrons emitted from the cathode are influenced by the electric and magnetic fields to follow a path through the anode-cathode space and pass in close proximity to the openings. A common resonator receives electromagnetic radiation induced in the openings as a result of the electrons passing in close proximity to the openings, and reflects the electromagnetic radiation back towards the openings to produce oscillating electric fields across each of the openings at a desired operating frequency.

摘要： An impulse radar guidance system and method for use with a spinning projectile. The system and method tracks the flight of the spinning projectile using an all-weather radar or tracker. A linearly polarized asymmetric waveform is transmitted at the projectile that comprises a series of repeating pulses having a relatively strong, short, positive electric field pulse followed by a relatively weak, long, negative electric-field baseline. The projectile contains a dipole antenna having a switching diode disposed between respective halves thereof. The waveform is reflected from the antenna which spins with the projectile and reflects a relatively strong signal when the electric field pulse of the asymmetric waveform is aligned along a conduction direction of the diode, a relatively weak reflected signal when the antenna and diode are aligned orthogonal to the electric field pulse, and a small, non-zero, signal when the diode is aligned anti-parallel to the electric field pulse and the diode is back-biased so that respective halves of the antenna are disconnected. The radar or tracker measures the instantaneous roll angle of the spinning projectile during its flight as a function of the state of the reflected signal. The projectile has a maneuvering device, and a receiver that receives commands that causes the maneuvering device to actuate at one or more specific roll-angles to deflect the flight direction of the projectile at a target.
