Simulating the Missile Guidance System

Running the guidance simulation demonstrates the performance of the overall system. The target is defined to be traveling at a constant speed of 328 m/s on a reciprocal course to the initial missile heading and 500 meters above the initial missile position. The data, shown in the figure below, can be used to determine if the missile can withstand the flight demands and complete the mission to impact:

The simulation results show that target acquisition occurs 0.69 second after search initiation, with closed loop guidance starting after 0.89 second. Impact with the target occurs at 3.46 seconds, with the range to target at the point of closest approach calculated to be 0.26 meter:
