Consisting of a tightly meshed network of short range Doppler weather radars, Distributed Collaborative Adaptive Sensing (DCAS) represents a new paradigm in meteorological sensing. Rather than sensing everything in a sit-and-spin manner, a DCAS system is an end-user driven sensor network that uses targeted sector scans to sense only those volumes that the end-users have indicated are important to their data needs. The advantage is that by limiting what is sensed, higher quality measurements are possible due to the ability to dwell longer, scan more elevations, obtain better multi-Doppler coordination, and sample at higher rates.
