摘要
Abstract
Array radar channel between the amplitude and phase inconsistency seriously degrade the performance of the array signal processing, the solution is added a calibration filter in the receiving channel. Calibration filter coefficients usually requires matrix inversion to obtain. Direct inversion, however, there is the matrix "Ill" problem, leading to no solution, despite the use of the generalized inverse method to solve, but the solution still exist problems of instability. A regularization method to solve the coefficient matrix of the "Ill-conditioned" is presented, and a regularization parameter solving method is given. Simulation results show that in the ease of " Ill-conditioned" , the method is still be able to obtain a stable, good calibration result, it is feasible and effective.关键词
