在被动测量的情况下,针对静止单站的纯仰角目标运动分析的问题,提出了一种纯仰角目标的非线性参数航迹的滤波新方法。通过设定目标的飞行模式,分析目标空间位置的三角函数关系,利用纯仰角序列建立起目标的非线性参数航迹,并确定其中的可观测参数。利用总体最小二乘法解算出相应的可观测参数,进而对后续时刻的目标仰角进行递推预测。仿真结果验证了新方法的有效性,对问题的后续解决提供了理论参考和借鉴作用。
In the case of passive measurement, aiming at the problem of pure elevation angle moving target of stationary single station, a new method of filtering nonlinear parameter track of pure elevation angle target is proposed. By setting the target flight mode, the trigonometric function of the target spatial position is analyzed, the target non-linear parameter track is established by the pure elevation sequence and the observable parameters are determined. The total least square method is used to calculate the corresponding observable parameters, and then the target elevation of the subsequent moment is recursively predicted. The simulation results verify the effectiveness of the new method and provide theoretical reference and reference for the subsequent solution of the problem.
