Abstract
A method and apparatus for determining the position of a target are disclosed. The method includes collecting onboard the platform a first set optical radiation in a first bandwidth and a second set of optical radiation in a second bandwidth reflected from a field of view; and determining the position of the target from the difference between the detected first and second sets of optical radiation. The apparatus includes a pair of detection channels a pair of detection channels, each of which further includes at least three optical channels, each detection channel capable of collecting onboard the platform a first set optical radiation in a first bandwidth and a second set of optical radiation in a second bandwidth, respectively, reflected from a field of view. The apparatus further includes a plurality of electronics capable of determining the position of the target from the difference between the detected first and second sets of optical radiation.
