Clutter rank estimation rule for MIMO radar with arbitrary transmitted waveform synthetic strategies

A computational-efficient estimated rule of clutter rank for multiple-input multiple-output (MIMO) radar with arbitrary transmitted waveform synthetic strategies is presented and proved. It is suitable for both conventional phased array radar and MIMO radar with a uniform sparse or non-uniform sparse transmitting subarray, and is also valuable for the design of optimal waveform synthetic strategies and space-time adaptive processing algorithms. The effectiveness of the proposed rule is verified by simulation results.
