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.
