Abstract

Hit-to-kill interceptor uses a millimeter wave radar seeker to image incoming targets before hitting it and select an aim point to strike. At different detection angles, imaging effect of the millimeter wave radar seeker on a target is quite different, which needs to be controlled. Aiming at the problem of detection angle control of the missile seeker on hit-to-kill interceptor, we have extended the proportional guidance and design a final guidance law with detection angle control, which can realize the interceptor to detect a target at a desired angle before hitting, thereby ensuring the imaging effect of the seeker. Meanwhile, considering the maximum steering angle limit of the seeker, we analyze the detection angle setting range of the guidance low and avoid the target loss caused by a too large detection angle. The effectiveness of this method has been verified by digital simulation results.

Key words： hit-to-kill interception; detection angle control; aim point terminal guidance
