On the trade-off between mainlobe width and peak sidelobe level of mismatched pulse compression filters for linear chirp waveforms

Abstract

In previous paper the authors introduced a technique for generating mismatched pulse compression filters for linear frequency chirp signals. The technique minimizes the sum of the pulse compression sidelobes in an Lp norm sense. It was shown that constant, extremely low sidelobe levels better than 60 dB can be achieved for minimal mismatch loss but with some broadening of the compression peak. This paper investigates the tradeoff between the sidelobe level and the mainlobe width for mismatched filters designed using Lp norm techniques.
