Abstract:

The sub-system failure can cause poor performance of active phased array,including the loss of gain and depravation of side-lobe level.With the normal distribution of random error on antenna elements of amplitude and phase in consideration,the variety of array performance is analyzed versus the antenna element failure,sub-array failure and TR module failure.Simulation results show that the deterioration of gain is less than that of side-lobe level,which are referential to the performance evaluation and project design of phased array antenna.

Key words: sub-system failure;active phased array;antenna gain;side-lobe level
