  • With the analysis of the ambiguity function for Discrete Frequency Code Waveform (DFCW) signals, the optimized model for DFCW design is established and the Micro swarm Particle Swarm Optimization (MicPSO) algorithm is proposed to design orthogonal discrete frequency-coding waveforms. As an arrangement issue, the DFCW design is optimized by using Grefenstette coding as MicPSO particle code. The simulated results show that, the DFCWs Auto-correlation Sidelobe Peak (ASP) and Doppler tolerance are mainly determined by the length of coded signal, and the cross correlation properties is greatly improved based on the optimization method described in this paper. Compared with existing methods, the proposed method can save processing time and obtain better optimization results.
