Claim:
1. A radar system configured to process a reflected signal detected by a radar antenna, said system comprising: a radar antenna, wherein the antenna includes a reference element, an alpha element spaced apart from the reference element by one half-wavelength of the reflected signal, and a beta element spaced apart from the reference element by an even number of half-wavelengths of the reflected signal; and a controller configured to receive detected signals from the reference element, the alpha element, and the beta element, determine an alpha phase difference between the detected signals from the reference element and the alpha element, determine a beta phase difference between the detected signals from the reference element and the beta element, and determine a first virtual phase difference that corresponds to the reflected signal expected to be detected by a first virtual element located halfway between the reference element and the beta element, wherein the first virtual phase difference is based on the beta phase difference divided by two.
