Abstract: The decision of the Canadian Army to move toward lighter vehicles with increased mobility and less conventional armour has stressed the need for the development of better detection and countermeasure systems to improve survivability. Recent work made at Defence Research & Development Canada (DRDC) has demonstrated the effectiveness of a second-generation Defensive Aids Suite (DAS) prototype against simulated threats including LBR, target designators, range finders, and missile plume simulators. The goals of the project were to develop a DAS prototype including a multi-function laser capable of laser dazzling, decoying, and jamming to augment the countermeasures suite available to the crew of a vehicle. This project was undertaken as part of the DRDC Future Armoured Vehicle System Technology Demonstration (FAVS-TD) program. The project succeeded in demonstrating a multi-function laser capability and its operation with a second-generation DAS demonstrator. The DAS prototype is an ideal platform to study the survivability of land vehicles in realistic operational scenarios.
