长基线统计MIMO雷达检测性能研究
A Study on Detection Performance of Long Baseline Statistic MIMO Radar
摘要
Abstract
In order to make full use of the spatial diversity of statistic multiple-input multiple-output (MIMO) radar,the detection method and performance of long baseline (antenna spacing and target detection range is comparable) statistic MIMO radar are studied.Firstly,the channel signal model of long baseline statistic MIMO radar is given according to the radar equation.Then the likelihood ratio test detector of long baseline statistic MIMO radar is derived according to Neyman-Pearson criterion.Finally,the detection performance of long baseline statistic MIMO radar is analyzed by the simulation of detection probability and coverage.The simulation results show that the detection performance of long baseline statistic MIMO radar is better than that of short baseline (the distance between the antenna is negligible when compared to target detection range) statistic MIMO radar.The research results have important reference value for the research of the system design,antenna placement and practical application of the statistic MIMO radar.关键词
