Orthogonal Polyphase Sequence Sets Design for Radar Systems

Multiple radar systems can fundamentally improve the system performance by using a group of specially designed orthogonal signals. A Modified Simulated Annealing Algorithm (MSAA) is proposed as a statistical technique for obtaining approximate solutions to combinatorial optimization problems. The Proposed algorithm is a combination of Simulated Annealing and Hamming Scan algorithms and this algorithm is used to design orthogonal polyphase sequence sets which have good autocorrelation and crosscorrelation properties. Some of the synthesized results are presented, and their properties are better than other known in the literature. The synthesized polyphase sequence sets are promising for practical application to multiple Radar systems. The convergence rate of the algorithm is also good.
