摘要
本文研究了一类混沌编码信号,利用混沌信号进行雷达信号的相位编码,并且计算了这类编码信号的模糊函数。理论和仿真结果表明,混沌编码信号的模糊函数十分逼近理想的“图钉型”,信号具有很高的时延和多普勒分辨力,揭示了混沌用于雷达信号处理的可能性和优越性。
This paper analyzes a kind of chaotic modulation signals, the phase-modulated radar signals are generated by chaotic signals, at the same time the ambiguity function of the coded signals is given. Theory and simulation results show that the ambiguity function of chaotic modulated signals is approximatly 'thumbtack-shape' as the ideal results, thus the signal has high resolution both in time- delay domain and Doppler frequency domain. It implies the possibility and advantages for chaos to be used in radar signal processing.
