Abstract:
A method for interpolated 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; interpolating signal instances; calculating a first target angle; and calculating a position of the tracking target relative to the radar array from the target range and first target angle.

Claim (Index 1):
A method for interpolated virtual aperture array radar tracking comprises:\n transmitting a first probe signal, the first probe signal having a first phase function; transmitting a second probe signal, the second probe signal having a second phase function; receiving a first set of signal instances corresponding to a first reflected probe signal at a radar array in response to reflection of the first probe signal by a tracking target, wherein the tracking target and radar array are connected by a target vector; wherein the radar array comprises a first plurality of radar elements positioned along a first radar axis; receiving a second set of signal instances corresponding to a second reflected probe signal at the radar array in response to reflection of the second probe signal by the tracking target; calculating a target range from at least one of the first and second reflected probe signals; corresponding the first set of signal instances to physical receiver elements of the radar array; corresponding the second set of signal instances to a first set of virtual elements of the radar array; wherein virtual elements of the radar array are described in terms of the physical elements of the radar array by an element translation function; generating a third set of signal instances by interpolating the first and second sets of signal instances; corresponding the third set of signal instances to a second set of virtual elements of the radar array; calculating a first target angle between a first reference vector and a first projected target vector; wherein the first projected target vector is the target vector projected into a first reference plane, the first reference plane containing both of the first radar axis and the first reference vector; and calculating a position of the tracking target relative to the radar array from the target range and first target angle.
