Abstract:

In order to solving the problem of ineffective clutter suppression and target detection of space-time adaptive processing(STAP) in bistatic airborne radar, a clutter pre-filtering method applied in the bistatic airborne radar that takes advantage of radar operating parameters, platform velocity and so on is proposed. The velocity error of the airborne platform is also considered. Most of the clutter can be filtered so that the residual clutter can be completely suppressed by the well-developed STAP algorithm. Computer simulation results show that this method is effectively workable to several classical geometric configurations of bistatic airborne radar. The moving target detectability of the following STAP algorithm is also enhanced after this pre-filter.

Key words: bistatic airborne radar, space-time adaptive processing(STAP), dimension-reduced, clutter suppression
