摘要： A compensated amplitude comparison monopulse receiver (10) having an angular measurement capability substantially unaffected by mismatches in channel transient response and target range tracking inaccuracy is disclosed herein. The inventive monopulse receiver (10) includes a first receiver channel (24) for impressing a first output voltage S1 on a first output port (28) thereof in response to excitation by a sum signal. A second receiver channel (26) impresses a second output voltage S2 on a second output port (30) thereof in response to excitation by the sum and a difference signal. In a calibration mode, a calibration source (22) provides a series of calibration pulses to the first and second channels (24, 26) which induces first and second calibration voltages to appear on the first and second output ports (28, 30) thereof. Sampling gates (32, 34) sample the first and second calibration voltages subsequent to application of each calibration pulse to the first and second receiver channels (24, 26). In a tracking mode the sample gates (32, 34) are operative to sample the first and second output voltages present on the first and second output ports (28, 30). The inventive receiver 10 further includes circuitry (48, 50) for calculating the angular location of the first object from the sampled first and second output voltages. A compensation network (36) then adjusts the calculated angular location on the basis of the sampled calibration voltages.

摘要： Radar systems that operate in accordance with the crossfeed method require an exact balancing of the individual Doppler frequency evaluation channels in the receiver. According to the invention, a special method is used first to make the amplitude levels in the individual channels equal to one another and then to determine and balance the phase differences between the channels. A radar system using this method is also described.

摘要： A monopulse radar comprising a pilot signal generator (20) for injecting phase and amplitude-defined pilot signals into the separate receiving channels (6-12, 3, 16-19) to obtain correction signals through the variation in the mutual phase and amplitude relationship between the separate receiving channels for correcting angle error signals derived from target return signals. The pilot signal generator (20) and the transmitter (1) are tunable and a control circuit is incorporated for adapting the pilot signal generator (20) relative to the frequency of the target return signals.

摘要： A system for automatically phase aligning parallel signal processing channels such as those used in the receiving system of monopulse radars, for example. Test signals having a predetermined phase relationship are applied at the inputs of each of two signal processing channels and a phase detector measures the phase of the resulting output signals. The phase detector''s output signal is processed to control a variable phase shifter, series coupled with the local oscillator signal applied to a mixer in one of these channels, so as to cause the test signals at the output of the two processing channels to have a predetermined phase relationship.

摘要： A monopulse radar receiver is disclosed wherein angle error digital computation apparatus is used for correcting received target return signals in accordance with digital correction signals which are derived within such receiver in response to pilot pulses. Such digital computation apparatus includes means for generating, from pilot pulses, digital signals representative of the pair of quadrature components of video signals developed in the sum channel and each one of the difference channels. The quadrature components associated with the target return signals are then corrected in accordance with the quadrature components associated with the digital correction signals.

摘要： A radar installation is provided in which the receiving aerial for the echoes is of the type used in monopulse radar, but in which the processing circuitry for delivering the required final information is of the character utilized in an electromechanical scanning system. The echoes picked up by the aerial are thus subjected to some of the conventional processing in monopulse systems and the three signals resulting from this partial processing are transformed into a single signal of the type delivered by an aerial of an electromechanical scanning radar.
