摘要: 僅有角度量測(cè)值的多傳感器系統(tǒng)對(duì)目標(biāo)的跟蹤方法有其困難之處，但它具有較廣泛的應(yīng)用背景。該文以不同載體上的兩部傳感器為例較系統(tǒng)地分析了這種情況下的關(guān)聯(lián)跟蹤和融合濾波方法。對(duì)于無(wú)干擾信號(hào)的情況，提出了傳感器的可用性矩陣，并給出了確定該矩陣的方法，建立了相應(yīng)的融合估計(jì)方程；對(duì)于密集干擾信號(hào)的情況給出了融合跟蹤門的建立方法和概率數(shù)據(jù)關(guān)聯(lián)濾波(PDAF)算法，并對(duì)相應(yīng)算法進(jìn)行了仿真驗(yàn)證。Abstract: Target tracking with angle only measurements is quite difficult, but there is a strong application potential. Based on the example of two passive sensors respectively on two moving platforms, this paper systematically analyzes the fusion method in such a circumstance. For sensors without spurious responses, the sensor availability matrix is put forward and the fusion estimate equation is established. For the circumstance of dense spu-rious responses, the idea of tracking fusion gate for application of PDAF filter are proposed for single target tracking. Simulation result verified the novel method.
