The Location Technology Research on Single Pulse Active Location Cooperate with Passive Location

Abstract

Abstract. The technology of combining single pulse active location with passive location, the question of accomplishing accurate target location as well as avoiding the problem that active detection signals are easy to be intercepted and identified need more research. The location performance and error distribution features of passive detection of remote target are analyzed in the issue at first. Then the location performance and error distribution features of single pulse active detection is put forward. In the end, the location system of single pulse active location cooperate with passive location is proposed. At the same time, the maximum likelihood estimation location result of the system is deduced and the location performance is analyzed. With the theoretical analysis and simulation approach proposed, single pulse active location system have high radial location accuracy, and the passive location system have high tangential location accuracy. Comprehensive location can have high radial location accuracy as well as high tangential location accuracy.

A Suboptimal Optimizing Strategy for Velocity Vector Estimation in Single-Observer Passive Localization

“…However, for passive nodes, changes in relative position can be observed. A common approach is to observe the periodic pulses emitted by a located node; the change in the pulse arrival time can reflect the variables of the radial vector [26]. When a passive node observes a change in the radial vector at constant intervals ∆t, the change in the radial vector between the two nodes can be expressed as…”
