Abstract :
A strapdown guidance system for low-cost precise guided munitions is presented using strapdown small field-of-view (FOV) seeker and miniature inertial measurement unit (MIMU). The three-dimension line-of-sight (LOS) dynamics are described using the missile-target geometric transformation. Due to the weakness of strapdown seeker, a hybrid differentiator is then introduced to obtain and filter the inertial LOS rate for proportional guidance law. The analysis and trajectory simulation results verify the performance of the proposed algorithm.
