Design of Clutter-Optimum Discrete Phase Coded Radar signals Via Integer Programming

摘要

The paper presents a method t o tackle the problem of designing discrete phase codes for the rejection of delay-Doppler clutter . Signal-to-Interference Ratio (SIR) has been used as t h e performance criterion and the maximization of SIR, for t h e case of coded rectangular pulse bursts , has been reduced to the minimization of a clutter integral. To solve the associated nonlinear optimization problem an integer programming algorithm has been adopted, using which it has been possible to obtain optimum signals for a variety of clutter distributions. The capability of the algorithm to provide optimum solutions inspite of the large number of local minima, makes it possible to design optimum discrete coded signals to reject arbitrary delay- Doppler clutter with moderate computational efforrs.
