摘要
主要研究空间监视相控阵雷达目标跟踪问题。针对LFM脉冲测距时由于距离-多普勒耦合而产生的系统偏差,采用修正测量方程的扩展卡尔曼算法,解决了非线性跟踪滤波问题,并利用Monte Carlo仿真实验验证了算法的有效性。
In this paper the problem of tracking target with space surveillance phase array radar is studied. Aiming at the systematic bias in ranging with LFM waveforms caused by range-Doppler coupling, the nonlinear filtering problem is solved by using EKF algorithm with modified measurement equation. Monte Carlo simulation verifies the efficiency of the algorithm.
