The Precision Analysis and Simulation Based on SLAM

Precision analysis is one of the key factors which must be considered in the process of Anti-air missile guidance system design . In this paper, a homing guidance system of anti-aircraft missile systems is analyzed, and finally statistical linearization adjoint method (SLAM) is chosen. Considering the system with disturbance of target maneuver, glint, atmosphere nois s and so on, a typical proportional navigation engagement simulation model is stablished. The simulation results show that the SLAM can not only get the root mean square miss distance, but also the total impact of the miss distance due to the different random input signal of the system, which results into a higher accuracy of guidance system in practice.
