Application of Different Guidance Laws to Pulse Trajectory Corrected Smart Munitions

The application of two kinds of guidance law to the terminal guidance stage of the pulse trajectory corrected smart munitions was researched. The pulsed proportional navigation (PPN) guidance and attitude pursuit guidance (APG) by the concept of zero effort miss (ZEM) were established, and the corresponding ignition control strategy of the pulse jet was presented. By using six-freedom-degree ballistic equations, the two cases of PPN and APG were investigated. Result of simulation indicates that under ideal circumstances. the method given by this paper is practicable and correct. and the analysis of the two schemes can provide helpful references for the future design.
