A pre-processor (10) for target trackers is disclosed which allows several image analysis algorithms to be computed simultaneously so as to provide improved real-time target recognition. The pre-processor (10) is also equipped to compensate for the rapid rotation of the target image when the tracking aircraft performs abrupt turning maneuvers.

Multi-function pre-processor for target tracking

An adaptive RADAR environmental signal filter (1) is described which selectively preprocesses RF RADAR input data prior to the data's utilization by a processor (8). The filter (1) consists of an array of parallel discriminator cells (165) which compare incoming RF RADAR data to a window parameterized by predetermined threshold values. The array of discriminator outputs are networked through combinational logic (59) in order to provide an output correlation signal (63) to an external processor (8). A discriminator enable latch (55) synchronizes the discriminator outputs as the outputs pass through the combinational logic (59).
