摘要： A pulse compression decoder which oversamples by two the signal elements of received phase-coded signal, performs a pairwise average on the signal elements at intervals equal to 1/2 the width of a signal element, reverse-codes the pairwise averages, combines the pairwise averages to form a sub-accumulation signal, and performs a pairwise average on the sub-accumulation signals at intervals equal to 1/2 the width of a signal element to produce a compressed pulse having a high peak-to-side lobe ratio.

摘要： A signal receiver employing constant false alarm rate (CFAR) circuitry is disclosed. The CFAR circuitry includes a dispersive delay line for stretching received echo signals, means for limiting the stretched echo signals and an inverse dispersive delay line for finally processing the stretched and limited echo signals. With delay lines of proper characteristics, the just-outlined processing of echo signals results in reconstituted signals, the amplitude of each one of such reconstituted signals being indicative of the source of a corresponding echo signal.

摘要： Pulse measurement of chirped radar returns is made before dechirping by these of a linear detector averaging circuits and time delay circuits such that the measurement is indicative of the RMS power of the pulse. Depending on the received chirp pulse different averaging circuits and time delay circuits are switched in so that its output is coincidental with the delayed dechirped signal. Output is encoded for a digital indication of the power and is fed through scalers to set the threshold of the video signal processor.

摘要： A coherent, 13 bit phase reversal pulse modulator and pulse compression filter for increasing the range resolution of a coherent radar. The transmitted pulse is subdivided into equal duration bits, and as the pulse is being formed each bit may or may not be shifted in phase determined by a digital code generator. The range resolution of which this pulse reversal modulated pulse is capable is achieved by processing the radar return signal in an approximation to a matched filter.

摘要： Phase coded pulse compression apparatus for processing pulsed radar information, in which the transmitter employs a modified code which, when delayed by a seleted number of code bits and combined with the undelayed modified code, provides a desired code. The receiver employs a phase detector both inputs of which are responsive to the received echoes of the transmitted modified code, one of the inputs being delayed relative to the other by an amount corresponding to one code bit, to provide a video output having the desired code. A video pulse compression decoder, responsive to the desired code and coupled to the pase detector, effects the desired pulse compression.
