Target Acquisition Probability in Midcourse and Terminal Guidance Handing-off for Cooperative Guidance of Missile

To quantitatively evaluate cooperative guidance efficiency for air-to-air missile,target-acquisition-probability for midcourse and terminal guidance handing-off were studied.Command amendment method was given,and six main error sources,including radar measurement error,attitude measurement error,navigation location error,transfer alignment error and command delayed error,were deduced based on vector means.The quantitative relationship between error sources and acquisition probability was obtained based on target-acquisition-probability computing model in midcourse and terminal guidance handing-off.Simulation about acquisition-probability and error sensitivity was carried out.Result shows that command delayed-error and radar measurement error of succeeded fighter are the main factors affecting target-acquisition-probability.
