Aiming at problems of low probability of interception and poor anti-jamming performance of the multi-output radar, the numerical simulation based on a chaos optimization algorithm is proposed. Firstly, chaotic frequency coding is applied to the multi-output radar signal, and different frequency modulation methods are applied to different subpulses. At the same time, in view of the low efficiency of the numerical simulation algorithm in large space and high dimensional optimization, the GASA algorithm is used to increase the diversity of chaotic optimization algorithm search process. According to the specific working mode, the initial phase of each cycle of the multi-output radar orthogonal waveform is obtained, and the number of numerical simulations of multi-output radar orthogonal waveforms is established by the Model. Experimental results show that the proposed method can improve the radar energy utilization and signal-to-noise ratio, allocate reasonably the transmitting energy, and keep the structural stability of the LFM signal frequency changing continuously with time.
