Simulation of search over terrain with unmanned aerial vehicles

In this report an unmanned aerial vehicle (UAV) is modeled and simulated. The objective is to investigate di erent search patterns for tactical use in operations with land and air units. Models developed are integrated into scenarios where one or several UAVs will perform reconnaissance missions over terrain. Scenarios are simulated with the simulation framework Flames. The focus has been on developing the aircraft model and the ight control system using Digital Datcom and methods from the literature. Reconnaissance is done with conventional search patterns using an optical sensor. Simulations will be used to evaluate requirements for e ective search missions. E ectiveness is de ned with a cost index in order to compare di erent scenario setups where sensor capacity and number of UAVs are varied. The result shows how the mission setup best is improved by adding sensor capacity and/or additional UAVs.
