分析了传统的正交化算法在干噪比较低时，干扰对消效果不佳的原因．将特征子空间分解技术与正交化算法相结合，提出了一种修正的正交化算法．仿真结果表明，所提出的算法极大地改善了低干噪比时的干扰对消性能．

The reason for deteriorated performance of conventional orthogonalization algorithms for adaptive jamming cancellation at low jamming to noise ratio (JNR) was analyzed.A modified orthogonalization algorithm based on a combination of eigendecomposition techniques and the orthgonalization algorithm was introduced.It is shown from the simulation results that jamming cancellation performance is significantly improved at lower JNR by using the proposed algorithm.
