Abstract :
An analysis of the effect of Doppler shift on the compression of nonlinear FM signals is presented based on the use of paired echoes. The analysis enables the observed distortion due to Doppler shift to be explained in terms of a series of echoes, each with the shape of the undistorted compression filter output.
