摘要：For the issue of engagement geometry, the modern guidance laws can attack the adversarial and high maneuvering targets. Robust geometric in modern guidance laws is based on the classical differential geometry curve theory and Lyapunov stability theory. For the maneuvering target, based on different geometry and Lyapunov stability theory, the ballistic of robust geometry method guidance law in pursuit of different of maneuvering targets are analyzed. Through simulation of proportional navigation law and robust geometric method in the pursuit of the same target with different emission angles, ballistic properties of the two guidance laws are analyzed. Comparing the simulation results of the two kings of guidance laws, advantages of the robust geometric guidance law are demonstrated as follows: no additional measurement information, easy to perform and different geometry, and the effectiveness of the guidance law for the line of sight rotation inhibition. Simulation results prove that trajectory of robust geometry is straighter, and distribution of required normal overload is reasonable. Robust geometry is a more precision and critical navigation law.
