Networked Waveform System for Range Velocity Ambiguity Mitigation

A networked waveform system is developed to overcome the fundamental limitation of a single pulsed Doppler radar in resolving ambiguities. The networked radar system uses the principle that the underlying intrinsic properties of the precipitation medium remain consistent in a network. The ambiguity in range and velocity is resolved by jointly processing the measurements from all the radars in the network. In this paper results for networked waveform system are shown for simulated data as well as data collected with first generation CASA (The Center for Collaborative Adaptive Sensing of the Atmosphere, an engineering research center established by the National Science Foundation) radars deployed in Oklahoma.
