1. A method for generating a high resolution two-dimensional (2D) radar image, comprising steps: transmitting a radar pulse by a transmit antenna at an area of interest; receiving echoes, corresponding to a reflection the radar pulse in the area of interest, at a set of receive arrays, wherein each array includes and a set of receive antennas that are static and randomly distributed at different locations at a same side of the area of interest with a random orientation within a predetermined angular range; sampling the echoes for each receive array to produce distributed data for each array; and applying a compressive sensing (CS) procedure to the distributed data to generate the high resolution 2D radar image, wherein the sampling and applying steps are performed in a processor.
