基于二維測向與波束形成結(jié)合的多目標跟蹤
MULTI-SIGNAL TRACKING BASED ON 2-D DIRECTION FINDING AND BEAMFORM
-
摘要: 陣列信號的偵察與跟蹤是兩個同樣重要的問題，本文就二維空間移動信號的跟蹤問題提出了一種穩(wěn)健而快速的跟蹤方法，即波束形成與定點信號子空間搜索相結(jié)合的方法，對二維空間中的多個信號同時進行跟蹤與波束形成，在分批數(shù)據(jù)處理的基礎(chǔ)上實現(xiàn)信號的跟蹤截取，從而提高信號的跟蹤能力。文中還通過平面陣對空間二維信號的接收響應(yīng)模糊性分析證明了算法的有效性。

Abstract: Spatial inspection and tracking are two important objects in the array signal processing field. A fast and robust tracking method for 2-D moving signals, which combines beamform and spectral peak searching is proposed. In the method, several spatial signals can be processed simultaneously. Furthermore, the effectiveness is demonstrated by computer simulation. -
