Effect of Channel Mismatch on STAP Performance
Image and Signal Processing, 2008. CISP '08. Congress（2008）
摘要
Channel mismatch, including amplitude and phase mismatch, has severely affected the performance of space-time adaptive processing (STAP). In order to ascertain the specification of the effects on STAP, theory analysis of relation between clutter covariance matrix (CCM) with and without channel mismatch is done based on the model provided by literature, and the effect to signal is also analyzed. In the end computer simulation about the STAP performance is done according to different channel mismatch parameters, and useful conclusions are received.
