However, for higher-altitude operations between 20,000 and 30,000 ft, Predator series UAVs will be best suited for performing search, rescue, and damage assessment missions during a 24-hour period, which might involve higher operating costs. Note that these Predators are equipped with electro-optical sensors, high-resolution IR cameras, and mini side-looking radars (SAR), which are best suited to obtain high-resolution images of the targets regardless of weather conditions. The coherent detection capability of a SAR yields exceptionally high-quality images, which are considered most desirable for search, rescue, and damage assessment missions.

The following steps must be taken into consideration: His t o ri C a l a s P eC t s o F Un m a n ned a eria l 25 • • • • • Problem statement Fire perimeter tracking for a single UAV platform Cooperative team tracking Simulation of data collection and evaluation Base station capability to deploy multiple UAVs to monitor the propagation of the fire in terms of intensity and wind direction • Conclusion The principal objective of this particular study is to explore the feasibility of deployment of multiple LASE UAVs and to cooperatively monitor and track the propagation of large forest fires.

The minimum latency (Δmin) corresponds to the time of flight between the point of interest and the base station. It is further interesting to know that the maximum latency is strictly dependent on the total time required to make an observation at the distance x 0 and to deliver the data to the base station. 5 Latency between updates for a point x0 on the perimeter of the fire. W. ) is essential to minimize the latency associated with fire perimeter measurements delivered to the base station by the team vehicles.
