摘要：One kind of extended proportional guidance law is presented. This guidance law can beused without restriction about the motion speed of missile and target, and this is a differentpoint with the classical proportional guidance law. In the case of random alter the trackingtarget curvature radius, compared with classical proportional guidance law under the properrandom quantity, the normal overload of trajectory is relatively small, and has certainadvantage, so the study has significant reference value in actual application. And interceptiontime and normal overload have good performance. Tracking performance for highmaneuverability target is better than the classical proportional guidance law. A targetintercepting simulation based on MATLAB of the proportional coefficients and line-of-sightangular velocities is generated to analyze the trajectory properties. The effect of guidancecoefficients on trajectory properties is studied. Through simulation, we simplify the problemby ignoring the actual factors so that a certain level of error is expected. The situation inpractical requires more in-depth analysis and research.
