Abstract
A data processor system for extracting and quantizing aimpoint data from a tored video display of a target tracking operation comprising an operator-controlled joystick by which an operator can superimpose, on a frame-by-frame basis, distinctive display symbols coincident with the aimpoint of the target tracking system and a selected target reference point. The processor includes a programmable calculator which converts the angular separation of the tracking and target reference points into corresponding linear (x, y) data coordinates and then automatically plots the aimpoint from successive display frames on a target silhouette. The programmable calculator also is able to perform a coordinate rotation in order to compensate for angular displacement between the orientation of the tracking system and the target, e.g. to compensate for roll of the aircraft on which a radar tracker is mounted.
