Abstract
A process and systems for constructing arbitrarily large virtual arrays using two or more collection platforms (e.g. AUX and MOV systems) having differing velocity vectors. Referred to as Motion Extended Array Synthesis (MXAS), the resultant imaging system is comprised of the collection of baselines that are created between the two collection systems as a function of time. Because of the unequal velocity vectors, the process yields a continuum of baselines over some range, which constitutes an offset imaging system (OIS) in that the baselines engendered are similar to those for a real aperture of the same size as that swept out by the relative motion, but which are offset by some (potentially very large) distance.
Claims20
A system for imaging one or more emitters from a target scene comprising;
- a first sensor system having the target scene within its field of view;
- a second sensor system having the target scene within its field of view;
- wherein at least one of the first and second sensor systems is moving resulting in a relative motion therebetween and further wherein a temporally-distributed virtual imaging array is established thereby for imaging one or more emitters within the target scene.
A process for imaging one or more emitters from a target scene comprising;
- receiving by a first sensor system having the target scene within its field of view, first signals indicative of one or more emitters in the target scene;
- receiving by a second sensor system having the target scene within its field of view, second signals indicative of one or more emitters in the target scene;
- wherein at least one of the first and second sensor systems is moving resulting in a relative motion therebetween, and further wherein a temporally-distributed virtual imaging array is established thereby for imaging the one or more emitters within the field of view.
