A DETECTION METHOD OF HIGH RESOLUTION RADAR TARGETS BASED ON POSITION CORRELATION
-
摘要: 本文研究了毫米波高分辨雷達雜波背景下目標信號的檢測問題,提出了基于高分辨雷達目標一維距離象位置-徑向距離相關信息的非參數(shù)檢測方法。該方法不但計算復雜度低,而且還具有檢測沿距離走廊上多個擴展目標的能力。通過毫米波高分辨步進頻率雷達實測數(shù)據(jù)證實,這是一種非常有效的擴展目標信號檢測方法。Abstract: This paper studies the problems which detect targets in the background clutters of millimeter-wave high resolution radar,and proposes a nonparametric detection method,which not only does less computation,but also is able to detect multiple extended targets along distance corridor,based on the position(range)orrelation information of one-dimensional range images of high resolution radar targets.The experiments,based on real data of millimeter-wave stepped frequency high resolution radar,have certified that the method presented is a very effective detection strategy for muliple extended targets.
