Polyphase Coded signal Design for Netted Radar Systems

A Modified Simulated Annealing Algorithm (MSAA) is proposed as a statistical technique to design polyphase coded signals for Orthogonal Netted Radar Systems (ONRS) which have good autocorrelation and cross correlation properties. This algorithm is a combination of simulated annealing and Hamming Scan algorithms. Some of the synthesized results are presented, and their properties are better than other known in the literature. The effect of Doppler frequency shift on the performance of these signals is investigated and found "thumbtack ambiguity function". The synthesized polyphase sequence sets are promising for practical application ONRS / multiple radar. The convergence rate of the algorithm is also good.
