Abstract
A seeker head comprises a seeker for scanning field of view and a gyro assembly sensing attitude variations. Signal processing means process information from two consecutive scans of the seeker. The signals from the gyro assembly are applied to a coordinate transformer circuit, which transforms the picture information from consecutive scans into a common intertial coordinate system. A target is selected by target selection logic. The coordinates of a selected target are read into a deviation memory. The signal processing means provide the inertial sight line rate of the sight line to a selected target. After each scanning and signal processing cycle the location is computed at which the target is to be expected according to the sight line rate measured during the preceding cycle. This permits comparison of target signals in consecutive scans even with moving targets, recovery of temporarily lost targets and discrimination between actual targets, such as an aircraft, and mocktargets, such as flares.
