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。

[Abstract]
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.
