In this paper, we investigate the problem of cancelling range-dependent clutter in bistatic radar by using multiple-input multiple-output (MIMO) techniques. The rotation and projection operations are applied directly to the received data samples to transform the range-dependent clutter to be range-independent. Only the velocities of transmitter and receiver are needed to aid the data processing. The method exploits the fact that the clutter spectra of bistatic MIMO radar are in a 3-dimension (3-D) plane when both transmitter and receiver are side-looking. Simulation and analysis show that the proposed method is easy to implement and can cancel the range-dependent bistatic clutter effectively.
