Abstract:

The performance of a disturbance covariance matrix is degradated in space time adaptive processing (STAP) when it is estimated with secondary data contaminated by targetlike signals. To solve the problem, a knowledge aided space time adaptive processing (KASTAP) scheme is presented,which incorporates knowledge sources of clutter with the general inner product nonhomogeneity detector (GIP NHD) in the secondary data selection of STAP. Simulation shows that the presented scheme screen out contaminated secondary data effectively and improve the performance of STAP.
