By synthesizing multiple frequency signals into a wideband signal, the Frequency Diverse Multiple-Input-Multiple-Output (FD-MIMO) radar can obtain higher resolution than ordinary MIMO radar. Furthermore, FD-MIMO radar can obtain higher resolution and better recovery performance by exploiting the sparsity of the targets. For moving targets with unknown velocities, the recovery performance based on Compressive Sensing (CS) would significantly degrade if the estimation accuracy of velocities is not enough. The authors propose a new approach of Adaptive Sparse Recovery via Velocity Estimation (ASR-VE) for multiple moving targets FD-MIMO radar imaging.
