该文提出了一种利用角度和多普勒频率的一发一收外辐射源定位体制,针对运动目标,给出了接收站的最优航迹规划。该文采用定位的位置误差(Geometrical Dilution Of Precision, GDOP)作为优化对象,具体分析2维目标定位的优化问题,通过一边估计目标一边优化接收站运动的方法,使用无迹卡尔曼滤波(Unscented Kalman Filter, UKF)估计目标的位置和速度,以达到在定位的各个时刻能够得到最优的定位精度。仿真实验验证了该方法的有效性。

A passive location method with one transmitter and one receiver using Direction Of Arrival (DOA) and Doppler measurements is proposed in this paper. The optimal trajectory analysis for the receiver is given for a moving target. The minimizing Geometrical Dilution Of Precision (GDOP) for target is used to analyze the optimal 2-D location. Unscented Kalman Filter (UKF) is used to estimate the position and velocity of the target by optimizing the receiver’s trajectory, and the optimal location can be obtained for every estimated moment. A computer simulation is used to illustrate the effectiveness of the proposed method.
