Computation of QAM radar transmit signals with low autocorrelation side lobes

Abstract

This paper lays out a technique for designing QAM codes for radar. It will be shown that the QAM codes designed by the algorithm described in this paper result in significantly better target profile estimation error than other similar codes. In addition a method will be described to write a QAM code as the coherent super position of PSK codes which should ease some of the practical implementation issues of QAM codes.
