| 摘 要： | 利用多种调制相结合构造混合波形技术在雷达信号处理上造成一定困难.根据混沌可加性思想构造一类基于混沌映射的混合混沌雷达信号,并与Logistic映射构成的混沌信号进行比较分析,证明该混合混沌信号具有良好的自相关特性,模糊函数呈现较为理想的"图钉型",具有较高的距离和速度联合分辨率.同时混合混沌雷达信号的构成简单,易于处理.

| Abstract: | It is difficult to make use of multiplicate modulation techniques to construct hybrid waveform in radar signal processing.A mixed chaotic radar signal is constructed based on mixed chaos map.Properties of the mixed chaotic radar signal are analyzed by Lyapunov exponent,correlation,and ambiguity function,which shows the mixed chaotic signal has good auto-correlation,and ambiguity function is shaped by ideal thumbtacks and good resolution in distance and speed. |

| Keywords: | chaos mixed chaos radar ambiguity function |
