Abstract: A method for displaying point-of-interest coordinate locations in perspective images and for coordinate-based information transfer between perspective images on different platforms includes providing a shared reference image of a region overlapping the field of view of the perspective view. The perspective view is then correlated with the shared reference image so as to generate a mapping between the two views. This mapping is then used to derive a location of a given coordinate from the shared reference image within the perspective view and the location is indicated in the context of the perspective view on a display.

The optical system includes at least one optical arrangement (34, 36a, 36b) defining a field of view (38a, 38b) of given angular dimensions and an optical switching mechanism (40) for alternately switching an optical axis of the imaging system between two directions (42a, 42b). The optical switching mechanism and the optical arrangement(s) are deployed such that the imaging sensor array generates images of at least two generally non-overlapping fields of view of equal angular dimensions and with diverging optical axes in fixed spatial relation. Rapid switching between the fields of view allows quasi-continuous monitoring of a larger field of view than would otherwise be possible while maintaining sensitivity to transient events.

Abstract: A system and method for protection of aircraft against surface-to-air missiles deploys sensors to provide coverage around an airport The use of a fixed (or slow moving) set of sensors around the airport allows detection of missile threats to all aircraft using the airport without requiring each individual aircraft to be provided with a threat detection system. Information about a detected threat is then typically transmitted in real time directly to the aircraft under threat to allow timely deployment of aircraft-based countermeasures. The detection system and method preferably employ spaced-apart sensors with overlapping fields of view to provide enhanced tracking through triangulation and reduced false alarm rates by redundancy of information. Airborne systems with overlapping coverage may be also used.
