1. An apparatus comprising:
a transmitter configured to transmit (i) a first probe signal and (ii) a second probe signal;
a receiver array configured to receive a first reflection of said first probe signal and a second reflection of said second probe signal; and
a signal processor configured to (i) link said first reflection to physical elements of said receiver array, (ii) link said second reflection to virtual elements of said receiver array, and (v) calculate object tracking parameters of a tracking target in response to a position of said physical elements and a virtual position of said virtual elements, wherein
(i) said first reflection of said first probe signal and said second reflection of said second probe signal are caused by said tracking target,
(ii) said transmitter generates said second probe signal having a phase function difference with respect to said first probe signal, and
(iii) said virtual position of said virtual elements is defined by (a) said position of said physical elements and (b) said phase function difference.
