Abstract :
There has been much interest in space-time adaptive processing (STAP) algorithms for the elimination of clutter in airborne radar systems. However, the performance of many practical STAP algorithms is severely degraded by the effects of the radar´s bandwidth. Time delay steering in both the spatial and Doppler dimensions is needed to mitigate these effects.
