Distributed Collaborative Adaptive radar network: Preliminary results from the CASA IP1 testbed

Current weather radar surveillance networks are based upon conventional sensing paradigm of widely-separated, standalone sensing systems using long range radars that operate at wavelengths in 5-10 cm range. Such configuration has limited capability to observe close to the surface of the earth because of the earthpsilas curvature but also has poorer resolution at far ranges. The center for Collaborative Adaptive Sensing of the Atmosphere (CASA) is founded on the transforming paradigm of distributed collaborative adaptive sensing (DCAS) networks designed to overcome this fundamental limitation. The Integrated Project 1 (IP1) is a four-node end-to-end system test bed aimed at precipitation and hazardous wind-sensing in southwestern Oklahoma. Some of the early observations of severe thunderstorm from the DCAS network in CASA IP1 test bed are presented in this paper.
