摘要
设计了一种基于Kent映射的混沌调频雷达波形,给出了如何通过Kent映射方程构造混沌调频雷达波形的方法,分析了其模糊函数特征及时频分布。理论分析与计算机仿真结果均表明,混沌调频波形是一种伪随机的雷达信号,具有"图钉型"模糊函数,具有很强的灵活性和反侦察性,具有更窄的压缩主瓣宽度与更低的副瓣电平。研究成果为雷达波形设计提供新的思路。
A chaotic FM radar waveform is designed based on Kent map, with the method of how to use Kent map equation method of constructing chaotic FM radar waveform. Its time frequency distribution and fuzzy function are analyzed. Theoretical analysis and computer simulation results show that the chaotic frequency modulation waveform is pseudo random signal radar, which has ＇ pushpin＇ fuzzy function, a strong flexibility and the ability of anti-reconnaissance, as well as side lobe narrower mainlobe width and lower compression. The research results provide a new i- dea for the design of radar waveform.
