Aiming at the limit of common miss distance measuring methods in common using, including optics-measuring, radio-measuring and GPS-measuring, estimation method of anti-ship missile miss distance based on the missile attitude angle, speed, and radar framework angle is studied. The estimation method and mathematical model are given through coordinate transformation by deducing the function of angle of sight and the known telemetry parameters. Miss distance is analyzed through using the previous telemetry data of range test, which shows the estimation method is correct, it is suitable for point radar garget, and that estimate accuracy is the same with GPS measuring accuracy. It not only is an auxiliary and a complement to traditional miss distance measurement method, but also is an inspection and a verification to the miss distance obtained by measuring data. The estimation method can be applied in range test.
