Space-Time Adaptive Processing is a key technology for moving target detection, but nonhomogeneity will cause the covariance matrix estimation error, which substantially results in the STAP performance degradation.

摘要空时自适应处理作为动目标检测的关键技术,但是非均匀环境将会造成协方差矩阵的估计误差,进而严重影响STAP性能。

In this paper, the maximum likelihood algorithm with process and measurement noise for nonlinear continuous-discrete system given by Jategaonkar and Plaetschke is improved in two aspects: 1 to avoid the disadvantages of sensitivities computation by common finite-difference method, in which the perturbation sizes should be selected optionally, an improved finite-difference method with best perturbations, is presented. 2 to improve the numerical stability of Jategaonkar's algorithm, maximum likelihood algorithm with fast triangular square-root decomposition filter is given.

摘要对Jategaonkar等人给出的同时计及过程及观测噪声的非线性连续-离散系统的极大似然算法从两个方面进行了改进:1给出了计算灵敏度的最佳摄动有限差分算法,避免了普通有限差分法计算灵敏度矩阵时需人为选择参数摄动量大小而带来的缺点;2给出了具有快速三角化平方根滤波的极大似然算法,提高了原算法的数值稳定性。
