Abstract:
A system for virtual aperture array radar tracking includes a transmitter that transmits first and second probe signals; a receiver array including a first plurality of radar elements positioned along a first radar axis; and a signal processor that calculates a target range from first and second reflected probe signals, corresponds signal instances of the first reflected probe signal to physical receiver elements of the radar array, corresponds signal instances of the second reflected probe signal to virtual elements of the radar array, calculates a first target angle between a first reference vector and a first projected target vector from the first reflected probe signal, and calculates a position of the tracking target relative to the radar array from the target range and first target angle.

Claim (Index 1):
A system for virtual aperture array radar tracking comprises:\n a transmitter that transmits first and second probe signals, the first probe signal having a first phase function and the second probe signal having a second phase function; a receiver array, comprising a first plurality of radar elements positioned along a first radar axis, that receives a first reflected probe signal in response to reflection of the first probe signal by a tracking target and a second reflected probe signal at the radar array in response to reflection of the second probe signal by the tracking target; wherein the tracking target and radar array are connected by a target vector; and a signal processor that calculates a target range from at least one of the first and second reflected probe signals, corresponds signal instances of the first reflected probe signal to physical receiver elements of the radar array, corresponds signal instances of the second reflected probe signal to virtual elements of the radar array, calculates a first target angle between a first reference vector and a first projected target vector from the first reflected probe signal, and calculates a position of the tracking target relative to the radar array from the target range and first target angle; wherein the virtual elements of the receiver array are described in terms of the physical elements of the receiver array by an element translation function; 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; wherein the signal processor calculates the first target angle by performing beamforming from the signal instances of the first and second reflected probe signals.
