This paper presents a hybrid evolutionary programming algorithm to solve the spread spectrum radar polyphase code design problem. The proposed algorithm uses an Evolutionary Programming (EP) approach as global search heuristic. This EP is hybridized with a gradient-based local search procedure which includes a dynamic step adaptation procedure to perform accurate and efficient local search for better solutions. Numerical examples demonstrate that the algorithm outperforms existing approaches for this problem. Categories and Subject Descriptors J.6 [Computer Applications]: Computer-aided Engineering. General Terms Algorithms, Design. Keywords Polyphase codes, code design, evolutionary programming, hybrid algorithms
