Abstract
A method for virtual aperture array radar tracking includes: transmitting first and second probe signals; receiving a first reflected probe signal at a radar array; receiving a second reflected probe signal at the radar array; calculating a target range from at least one of the first and second reflected probe signals; corresponding signal instances of the first reflected probe signal to physical receiver elements of the radar array; corresponding signal instances of the second reflected probe signal to virtual elements of the radar array; calculating a first target angle by performing beamforming from the signal instances of the first and second reflected probe signals; and calculating a position of the tracking target relative to the radar array from the target range and first target angle.
