The augmented proportional navigation guidance law(APNGL), which is widely used at present, has poor robustness and large miss distance when it against escape target with large overload at the end of the trajectory. In order to solve this problem, firstly, the planar guidance model is established, a new guidance error is defined. Secondly, based on the principle of parallel approach method, a sliding mode adaptive guidance law is designed. In this process, there is no need to assume a target motion model or maneuver style, so the new guidance law is robust to target maneuvering and is suitable for engineering application. Thirdly, the miss-distance-index (MDI) is defined to evaluate the miss distance, and the guidance parameters are adjusted adaptively according to MDI. Finally, digital simulation was done in planar and 6-DOF, simulation results show that the designed guidance law has excellent guidance performance and can greatly reduce the average miss distance (the maximum can be more than 60%).
