Future weather radar systems will need to provide rapid updates within a flexible multifunctional overall radar network. This naturally leads to the use of electronically scanned phased array antennas. However, the traditional multifaced planar antenna approaches suffer from having radiation patterns that are variant in both beam shape and polarization as a function of electronic scan angle; even...
This paper describes the X-band Phase-Tilt Radar antenna array being developed at the Engineering Research Center for the Collaborative Adaptive Sensing of the Atmosphere (CASA) for use in distributed, collaborative and adaptive sensing (DCAS) networks. The architecture of the radar and its component parts including the T/R module, passive antenna elements, and array controller are described in detail...
