Failure compensation based on rectangular cut and linear programming for 2-D solid-state active phased arrays

A novel method of failure compensation is presented for 2-D solid-state active phased arrays. Based on the failure element rectangular cut and linear programming, it is suitable for real-time compensation of any multi-elements failure distribution. In the case of maintaining the array´s two main-plane side-lobes equal to the ideal ones, the array average side-lobe level (AVSLL) is optimized by linear programming. Due to the real algorithm, only the array non-failure element amplitude will be adjusted. The theoretical analysis and simulated calculation results show that this method is suitable for practical engineering applications.
