匹配滤波器对检测前跟踪性能的影响
Impact of Matched Filter on Performance of Track-before-detect
摘要
Abstract
In order to improve the performance of track-before-detect based on Bayesian theory,this paper analyzes the impact of time and frequency domain response of matched filter on the performance of track-before-detect based on Bayesian theory,and gives a detailed process flow of track-before-detect based on Bayesian theory that uses time and frequency domain response of matched filter.It analyzes in detail the mechanism of observed signal and establishes appropriate observation model based on time and frequency domain response of matched filter,which avoids the performance loss of track-before-detect based on Bayesian theory resulted from the mismatch of observation model.The computer simulation shows that the performance loss of track-before-detect based on Bayesian theory can be avoided by using time and frequency domain response of matched filter.关键词
