Optimizing Guidance Strategy for Gun Launched Underactuated Weapons



This paper presents a guidance strategy for the control of underactuated mortar. The performance will be evaluated as compared to the traditional guidance law Proportional Navigation (ProNav) and the Impact Point Prediction (IPP). Performance and optimizations of the guidance law based was evaluated using a six degree-of-freedom (6-DOF) simulation environment for a 120mm guided mortar. Effectiveness of each guidance law for a guide-to-hit mission was assessed using Engagement Footprint Ratio (EFR) and Monte Carlo analysis in the simulation environment. Relative performance of the guidance strategies is presented and this comparison is used to demonstrate the effectiveness of each of the strategies in achieving target intercept by a guided mortar with limited control authority.
