Slow-moving Target Detection Method with FDA-MIMO Radar Based on Doppler-spreading Effect

It is difficult to distinguish the Doppler frequency between clutter and slow-moving targets when airborne radar is looking down, which makes it difficult to perform detection. To solve this problem, an frequency diverse array multiple-input multiple-output (FDA-MIMO) radar slow-moving target detection method Doppler-spreading (DS) effect is proposed in this paper. FDA-MIMO radar clutter and ground moving target signal models are established. Using DS effect, clutter and slow-moving targets are separated in the Doppler domain, and then clutter suppression and target detection are effective. Simulation results confirm the efficacy of the proposed method.
