A pulse compression system based on the transmission of a step approximation to linear FM pulse, and the subsequent processing of echos therefrom by converting the echo pulses I and Q baseband signals and then sampling these I and Q signals at the Nyquist sampling rate. It has been discovered that this processing yields a signal with a spectrum substantially identical to the spectrum of a properly sampled Frank coded pulse. These sampled I and Q signals are then compressed by a Fast Fourier Transform compressor to yield a pulse with low sidelobes. Author
