Claim 0:
1. A mobile vehicle mounted system for determining positioning and orientation of said mobile vehicle within an environment, comprising:
a transmitter;
a two-dimensional receiver array including at least three receivers,
said transmitter directing energy at an environment, said environment reflecting energy back to said at least three receivers, said at least three receivers capturing and digitizing said reflected energy; and
a digital processing unit in communication with said transmitter and said two-dimensional receiver array, said digital processing unit creating a coherent two-dimensional image from the digitized reflected energy captured by each of said three receivers and producing a plurality of two-dimensional interferograms from a plurality of pair-wise combinations of said created coherent two-dimensional images,
said digital processing unit further processing the plurality of two-dimensional interferograms to produce estimates of error of the position and orientation of the mobile vehicle relative to the expected system position and orientation and incorporating said errors into a navigation solution of said mobile vehicle.
