Due to seeker delay and coupling with body motion, a strapdown seeker has not been widely used for missiles though it makes the missile cost cheaper. In this paper, a homing loop design based on PID controller for missiles with a strapdown seeker is suggested. The PID controller produces body rate command, instead of estimating line-of-sight(LOS) rate for the proportional navigation guidance. Stability analysis for linear homing loop has been done to select controller gains. The performance of the designed terminal homing loop for a small tactical missile against a moving target, where the missile's strapdown seeker includes uncertain image processing delay, is verified through full nonlinear 6-DOF simulations.
