Target Resolution in Distributed Sensor Systems

Remote Situation Awareness capabilities using a field of microsensors are now feasible using recent electronics and communications improvements. For instance, the DARPA SensiT program is based on the concept of cheap, small, and smart devices that host multiple types of onboard sensors, which also possess considerable embedded processing and storage capability, and short-range wireless communications. The devices will be quickly and flexibly deployed for varying missions, potentially in very large numbers, on buildings and bodies, on vehicles, and on ground and under water. Power consumption is critical to surveillance lifetime as well as packaging and deployment techniques. Collaborative processing approaches that build on local collaboration between sensors are attractive because they restrict most communications to near-by sensors, minimizing communication energy requirements and decreasing the possibility of detection and jamming.
