摘要
初步分析了混沌信号(以Logistic为例)应用于测量中的主要特性。仿真分析了Logistic信号的频谱特性、相关特性、模糊函数。说明了混沌信号在具有较高的距离速度分辨力,同时具备强抗干扰性。对比分析了混沌码和伪随机码的多普勒容限能力。初步分析Logistic信号的抗干扰特性。
Some main measuring performance are researched based on the Logistic chaos signal. The correlation, spectrum and the ambiguity function associated with the Logistic signals are analyzed. It is confirmed that the chaos signal inspired by digital chaotic sequence provide strong anti-jamming performance and excellent resolution of distance and velocity. A comparative analysis between chaostic code and Pseudo-random Code is been done on the ability about Doppler sensitive. The anti-interference property of Logistic chaos signals is analyzed.
