Abstract :
A convenient formula for the estimation of clutter degrees of freedom is derived in wideband multiple-input and multiple-output (MIMO) radar with frequency diversity waveforms. The estimation of the clutter rank of MIMO radar is extended to the mode of the wideband with the help of the time-bandwidth product lemma; this could be valuable for designing an optimal technique in the application of parameter estimation, target recognition etc. The proposed rule is well verified by simulation results.
