Abstract

PURPOSE:To perform processing as one target even when a primary and a secondary radar video signal vary in mutual range, by recognizing the processing state between both the video signals with regard to not only the same range, but also adjacent range during their correlation arithmetic. CONSTITUTION:Video signals from a primary radar PSR and a secondary radar SSR are quantized by quantization parts 20 and 21, whose outputs are supplied to correlation arithmetic parts 23 and 24 respectively. Both the arithmetic parts 23 and 24 perform processing starting at a closer target when targets PSR and SSR at close range are handles simultaneously, or completes the processing regarding both the targets when they are handled at the same distance, thereby sending the result to a total correlation arithmetic part 26. When an input is received, the arithmetic part 26 sends the input information to the arithmetic parts 23 and 24 when there is a target being handled behind the target, or outputs the information to a buffer part 27 when not.
