Wideband MIMO Radar Waveform Optimization Based on Range Profile

Aiming at the signal bandwidth design problem for multi-target imaging task, a kind of multiple input multiple output (MIMO) radar waveform design method is proposed. At first, the closed-loop feedback between the range profile and the signal bandwidth, which can design the minimum bandwidth of a transmitting signal that can distinguish each scatterer of the target in range direction, is established. Then, considering the request of beam pattern and the bandwidth limitation, a waveform optimization model is established and solved. Therefore, the multi-target observation and the dynamic adjustment of the signal bandwidth are accomplished. In the end, the simulation results prove the performance of the algorithm in a low SNR circumstance.
