Since the spectrum of the ground clutter in an airborne multiple input multiple output (MIMO) radar is spatially-temporally coupled with each other, a space-time adaptive clutter canceller (STACC) is proposed for suppressing the clutter, which is an extension of the traditional clutter canceller in the ground-based radar to the moving airborne radar platform. By using the clutter echoes within pulses, the coefficient matrix of the clutter canceller is constructed. As a spatial-temporal anti-ground clutter pre-filter before an MIMO space time adaptive processing (STAP) algorithm, the proposed method can significantly suppress the ground clutter and potentially increase the output ratio of signal to clutter plus noise (SCNR). The experimental results demonstrate that the space-time adaptive clutter canceller can enhance the performance of the target detection not only for the side-looking radar, but also for the non-side-looking radar.
