System Requirements for Phased Array Weather Radar
Preamble This is the final report to Lockheed Martin on the requirements for a phased array weather radar. Discussed herein are those meteorological requirements that need to be met by weather radars having either reflector type antennas or active phased array elements. These requirements impact the design of the antenna, the transmitter-receiver, and signal processor. Justifications for these ...
متن کاملRefractivity Measurements from Ground Clutter Using the National Weather Radar Testbed Phased Array Radar
In warm seasons, convective precipitation initiation heavily depends on moisture near the surface [e.g., Dabberdt and Schlatter, 1996; Koch et al., 1997]. A necessary condition for an accurate prediction of convective rainfall is a good forecast of where and when convection will develop. Both prediction and understanding of convection is limited by the lack of high spatial and temporal resoluti...
متن کامل8.2 New Weather-surveillance Capabilities for Nssl’s Phased-array Radar
The U.S. Government operates seven distinct radar networks providing weather and aircraft surveillance for public weather services, air traffic control, and homeland defense. A next-generation, multifunction phased array radar (MPAR) concept has been proposed that could provide enhanced weather and aircraft surveillance services with potentially lower life-cycle costs than multiple single-funct...
متن کاملGPS Multipath Mitigation Using a Three Dimensional Phased Array
Digital beam steering with a phased array has previously been demonstrated to improve the Signal/Multipath (S/M) level for precision applications by providing gain in the direction of the GPS satellites. A disadvantage of using horizontal planar antenna arrays is that the beam pattern is symmetric in the Up/Down directions. This means that only the phased array ground plane affects the antenna ...
