This paper investigates the parameter coupling of range, Doppler, and direction of arrival (DOA) for wavelength diverse (WLD) multiple-input multiple-output (MIMO) radar with time-division multiplexing (TDM). In particular, the Cramér–Rao Bound for such a WLD-MIMO system is calculated and used for a novel array and wavelength design approach. Furthermore, a multitarget DOA estimation algorithm is presented, which can handle the WLD- and TDM-induced parameter coupling. Finally, simulations demonstrate the performance of the proposed method and the benefit over traditional MIMO.
