首先分析了阵列天线因单元（或单元群）失效引起的副瓣恶化和增益损失，然后用ＢＦＧＳ最优化算法对失效单元（或单元群）附近部分正常单元的幅相进行适当调整。结果表明，这种调整对由于单元失效引起的副瓣电平恶化有较好的补偿效果。

In this paper, the sidelobe degeneration and gain loss of phased array antenna caused by element or elements failure are analyzed firstly, then the BFGS algorithm is applied to regulate the amplitude and phase of the remaining elements in close proximity to the failed elements. It shows that such regulation have a good compensation effect on the sidelobe degeneration caused by element failure.
