Proportional navigation (PN) method is a kind of wide-used guidance law in large number of guidance problems, since it is very easy to implement whether on mathematical deduction or the online calculation. However, common PN method choose constant guidance coefficient which becomes the main weak-point. This paper introduces a changing-coefficient PN law which can be adaptive to uncertainties and disturbance, furthermore it can change impact angle based on different demand Besides, a new kind of parameter-selecting method was proposed which can solve the parameter-selection problem in guidance-law design procedure. Numerical simulation for the new guidance law was carried out, and compared to traditional guidance method (constant coefficient) to demonstrate the simplicity, robustness, and doable performance.
