A network based attenuation correction system for networked dual polarization radar observations

摘要

Electromagnetic waves backscattered from a common volume in networked radar systems are attenuated differently along the different paths. A network based attenuation correction system for a network of dual polarization radars can be developed by combing the conventional network approach and the conventional differential propagation phase based attenuation correction technique. The network based attenuation correction system proposed here has been evaluated by data from the Adaptive Sensing of the Atmosphere (CASA) Integrated Project 1 (IP1) radars, which is a radar network that can observe a weather event simultaneously by multiple radars in different locations. The preliminary results show that the network based attenuation correction algorithm retrieves reflectivity and differential reflectivity properly.
