摘　　要：针对新型无源探测系统中单站无源定位问题,建立了基于多普勒频率变化率的固定单站对运动目标的定位和跟踪模型,并对该模型应用修正增益的扩展卡尔曼滤波算法(MGEKF)对原始滤波结果进行处理.计算机仿真结果验证了该方法的稳定性和有效性.To solve the problem of single station passive location in the new passive detecting system, we developed a new location and tracking model for moving targets on the basis of fixed single station with Doppler frequency changing rate. Then we employed this model to deal with the primitive location results with the MGEKF algorithm. Computer simulations outcome verified the stability and availability of this method.
