Orthogonal pulse compression code design for waveform diversity in multistatic radar systems

Abstract

This paper deals with an orthogonal pulse compression code set design problem in multistatic radar systems. Multistatic radar systems can improve radar performance by using a set of orthogonal waveforms with the same operating frequency. We provide the signal model for multistatic radar system using a set of orthogonal pulse compression codes. Moreover, a novel algorithm is proposed to obtain the set of orthogonal pulse compression codes. This algorithm minimizes the sidelobe peak of sum of autocorrelation and crosscorrelation function while maintaining the orthogonality of each code. Some of the designed results are presented by evaluating the characteristics of autocorrelation and crosscorrelation functions. In addition, the waveform diversity system and non-waveform diversity system are compared in terms of the probability of detection performance.
