Filter Design for Strapdown Homing Guidance System

A strapdown homing guidance system for some ammunition was described. A strong tracking Kalman filter was designed for the strapdown homing guidance system using the information measured by the strapdown seeker to estimate relative movement variables between the ammunition and target. Then an optimal proportional law, which uses the estimated information, is used to guide the ammunition. Simulation results show that the strapdown homing guidance system with strong tracking Kalman filter could attack the maneuvering target effectively, and satisfy the performance indexes for the guided ammunition system.
