本文分析了一种混沌调制信号，这种调相雷达信号是由混沌信号产生的。文中还给出了编码信号的模糊函数。理论和仿真结果表明，混沌调制信号的模糊函数近似于“图钉形”，达到了理想的效果。因此，信号在时延域和多普勒频域都具有高分辨率。这说明混沌在雷达信号处理中应用的可能性和优越性。
This paper analyzes a kind of chaotic modulated signal, these phase modulated radar signals are generated by chaotic signals. The ambiguity function of the coded signals is also given. Theory and simulation results show that the ambiguity function of the chaotic modulated signals is approximately "thumbtack-shaped" for the ideal result. Thus the signal has high resolution both in the time-delay domain and the Doppler frequency domain. It implies the possibility and advantages for chaos to be used in radar signal processing.
