Abstract: The optimization design of integrated signal plays an important role in modern radar and jammer integration system. According to the characteristics of Pseudo-random signal, the bi-phase sequences are generated using spatiotemporal chaos system. Meanwhile, the optimization model is constituted based on the design principles of integrated signal. The chaos genetic algorithm based on adaptive choice strategy is applied to solve the model and the calculation steps are presented in detail. The idiographic examples are analyzed and the simulation results show that the improved chaos genetic algorithm is valid and applicable for the optimization design of radar and jammer integration signal.
