Abstract:

A method, and a system responsive thereto, is disclosed for determining the height and range of targets, particularly low altitude targets. The method depends upon the occurrence of a subrefractive atmosphere causing an inferior mirage image which is utilized along with the real image in a ray tracing technique with the cross-over points yielded therefrom being indicative of the height and range of the target being detected.
