1. A method for radar tracking using an interpolated virtual aperture array, comprising the steps of:
transmitting a first probe signal having a first phase function;
transmitting a second probe signal having a second phase function;
generating first reflected data in response to a reflection of said first probe signal from a target received at physical receiver elements;
generating second reflected data in response to a reflection of said second probe signal from said target received at said physical receiver elements;
determining a range of said target from said physical receiver elements based on at least one of (a) said first reflected data and (b) said second reflected data;
generating interpolated signal data in response to an interpolation of said first reflected data and said second reflected data; and
determining a position of said target relative to said physical receiver elements based on (a) said first reflected data, (b) said second reflected data, (c) said interpolated signal data and (d) said range.
