Abstract : An MTI radar based on a comparison of the Doppler shifts of the original signal and a phase reversed signal using pulse compression wherein the received signal is phase detected for in phase and quadrature components relative to the IF. A Doppler corrected pulse compressor produces a magnitude signal for the Doppler shift of the received signal from the sequence of in phase and quadrature components. Another Doppler corrected pulse compressor produces a magnitude signal for the Doppler shift of the received signal from the conjugates of the sequence of in phase and quadrature components. The magnitude signal of the same Doppler shift of the two compressors are compared and the difference is the output of the MTI.
