线性调频信号的相关检测性能分析
Correlation Detection Performance Analysis for Linear Frequency Modulation Signal
摘要
Abstract
According to the possible difference of Linear Frequency Modulation(LFM) signal parameter between repetition and Signal of Interest (SOI), the complex ambiguity function and cross correlation function when the deviation between repetition and SOI is existed are given. The influence of phase difference, frequency offset and chirp rate offset on performance analysis of correlation detection is analyzed. The conclusion indicates phase difference has no effects on detection and the detection probability decreases with the increase of frequency offset and chirp rate offset.关键词
