Claim 4:
5. A method of determining positioning and orientation of a mobile vehicle within an environment, comprising:
providing a transmitter;
providing a two-dimensional receiver array including at least three receivers and a digital processing unit in communication with said transmitter and said two-dimensional receiver array;
directing energy at an environment using said transmitter;
capturing a reflection of said energy reflected by said environment using said at least three receivers, said at least three receivers capturing and digitizing said reflected energy;
transmitting said digitized reflected energy to 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.
