摘　　要：可观测性分析是跟踪系统进行目标跟踪的前提和基础,只有满足可观测条件才能对系统进行正确求解,从而实现对目标的有效跟踪。针对多(三部或以上)基阵纯方位非机动目标跟踪系统的非线性特点,将观测方程伪线性化后,应用线性系统可观测性判定定理对系统的可观测性进行系统分析,并得到该系统的可观测性判定条件,仿真验证了所得结论的正确性。Analysis on obsevability of tracking system is the premise and basis of target tracking, only if the observable condition is fulfilled, could the system have correct solution, and the effective tracking of target could be realized. Aiming at the nonlinear characteristic of non-maneuvering target tracking system based on multiple（ three or more） arrays bearings-only,after the pseudolinear processing is applied on the observable equation as well as the observable condition of judging for linear system is applied to the tracking system, the observable condition of judging for this system could be obtained, the correctness of the conclusion is verified by simulations.
