摘要： A narrow field electromagnetic sensor system and method of sensing a characterisitc of an object such as density, thickness, or presence, for any desired coordinate position on the object. The sensor employs a transmitter (120) for transmitting a sequence of electromagnetic signals in response to a transmit timing signal, a receiver (110) for sampling only the initial direct RF path of the electromagnetic signal while excluding all other electromagnetic signals in response to a receive timing signal, and a signal processor (181) for processing the sampled direct RF path electromagnetic signal and providing an indication of the characteristic of an object. Usually, the electromagnetic signal is a short RF burst and the obstruction must provide a substantially complete eclipse of the direct RF path.

摘要： A radar range finder and hidden object locator is based on ultra-wide band radar with a high resolution swept range gate. The device generates an equivalent time amplitude scan with a typical range of 4 inches to 20 feet, and an analog range resolution as limited by a jitter of on the order of 0.01 inches. A differential sampling receiver is employed to effectively eliminate ringing and other aberrations induced in the receiver by the near proximity of the transmit antenna (10), so a background subtraction is not needed, simplifying the circuitry while improving performance. Techniques are used to reduce clutter in the receive signal, such as decoupling the receive (24) and transmit cavities (22) by placing a space between them, using conductive or radiative damping elements on the cavities, and using terminating plates on the sides of the openings. The antennas can be arranged in a side-by-side parallel spaced apart configuration or in a coplanar opposed configuration which significantly reduces main bang coupling.

摘要： A bi-static radar configuration measures the direct time-of-flight of a transmitted RF pulse and is capable of measuring this time-of-flight with a jitter on the order of about one pico-second, or about 0.01 inch of free space distance for an electromagnetic pulse over a range of about one to ten feet. A transmitter (53) transmits a sequence of electromagnetic pulses in response to a transmit timing signal, and a receiver (58) samples the sequence of electromagnetic pulses with controlled timing response to the samples. A timing circuit supplies the transmit timing signal to the transmitter and supplies the receive timing signal to the receiver. The receive timing signal causes the receiver to sample the sequence of electromagnetic pulses such that the time between transmission of pulses in the sequence and sampling by the receiver sweeps over a range of delays.

Date Feb. 4, 1993.A method of obtaining oceanographic and meteorological data from high frequency radar spectral information comprising the steps of transmitting a plurality of signals to a remote location, recording signals backscattered from the said location, generating a family of Doppler cluter spectra from the recorded backscattered signals and analysing the Doppler clutter spectra in terms of a model or models to detect the presence of rainfall. The model or models identify the presence of rainfall by detecting a reduced amplitude in some parts of the Doppler spectrum, especially in the "wings" of the spectrum by which is meant the regions where the magnitude of the Doppler shift is greatest. The method may also be used by detecting opportunity signals scattered from a remote location.

摘要： Disclosed is a method of mitigating the effects of anomalous propagation in a Radar system, comprising the steps of: receiving a plurality of returns from a plurality of transmit pulses; calculating a difference in magnitude between each of the plurality of returns and its successor; if one of the calculated differences indicates a first step change greater than a first predetermined threshold, calculating a first average magnitude of the returns received after the first step change, and replacing the returns received before the first step change with synthesised returns having a magnitude equal to the first calculated average magnitude.

摘要： A process for reducing erroneous plots when detecting targets using High Frequency surfacewave radar (HFSWR) is provided. Detection of genuine targets is thereby enhanced. A first difference in range of an apparent target is determined, based on range data, associated with the apparent target. A second difference in range of the apparent target is determined, based on Doppler data, associated with the apparent target. The first and second range differences are compared to one another over time to assess a consistency therebetween.
