One kind of extended proportional guidance law is presented. This guidance law can be used without restriction about the motion speed of missile and target, and this is a different point with the classical proportional guidance law. In the case of random alter the tracking target curvature radius, compared with classical proportional guidance law under the proper random quantity, the normal overload of trajectory is relatively small, and has certain advantage, so the study has significant reference value in actual application. And interception time and normal overload have good performance. Tracking performance for high maneuverability target is better than the classical proportional guidance law. A target intercepting simulation based on MATLAB of the proportional coefficients and line-of-sight angular velocities is generated to analyze the trajectory properties. The effect of guidance coefficients on trajectory properties is studied. Through simulation, we simplify the problem by ignoring the actual factors so that a certain level of error is expected. The situation in practical requires more in-depth analysis and research.
