摘要

本文分析了一类混沌调制信号，这些相位调制雷达信号是由混沌信号产生的。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为“图钉形”，从而达到理想效果。因此，该信号在时延域和多普勒频域都具有较高的分辨率。这说明了混沌技术应用于雷达信号处理的可能性和优越性。

Ambiguity function of chaotic phase modulated radar signals

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.
