复合线性调频信号的模糊函数分析
Analysis of Ambiguity Function of Combined Linear Frequency Modulation Signal
摘要
Abstract
In order to improve the joint distance-velocity-resolution of the single slope linear frequency modulation (LFM) ,a composed linear frequency modulation radar signal composed of chirp up and chirp down slopes is proposed. The ambiguity functions of the composed linear frequency modulation signal and the single slope linear frequency modulation signal are deduced and analyzed. The simulations of the two kinds of signals about the ambiguity function, - 3 dB ambiguity graph, distance ambiguity graph and velocity ambiguity graph have been presented and compared. The differences of them show that the composed linear frequency modulation radar signal has a better performance on velocity resolution and joint distance-velocity-resolution than the single slope linear frequency modulation radar signal.关键词
