Spread Clutter Mitigation via Knowledge-aided STAP in Miltiple-Input Single-Output System

摘要：

In Multiple-Input Single-Output (MISO) HF surface wave radar system, the fact that bistatic operation and the movement of the receiver platform causes the nonstationarity and spreading of sea clutter, which will lead to the difficulty in detecting those immerged targets. The space-time distribution of sea clutter in different geometry is firstly investigated; and a knowledge-aided STAP scheme is proposed for mitigating the clutter. The weights of different range bins are acquired from both the clutter priori and the prefiltered training data by direct data domain (DDD) algorithm. Numerical simulation shows the proposed scheme effective.
