Integration of UHF profiler information with bistatic measurements.

摘要

The McGill/Oklahoma University Bistatic Radar Network provides Doppler velocity measurements from three different points of view. This, in principle, allows a three-dimensional wind field retrieval. Because the receivers are looking at low elevations, the vertical component of the wind is poorly sampled and is mainly obtained by integration of the continuity equation with great associated uncertainty. The retrieval can be improved with measurements taken by a vertically pointing Doppler radar.;In this work, we study the impact on the reconstruction of the wind field when UHF wind profiler information is used as an additional constraint along with bistatic measurements. Experiments were done with a synthetic wind field to study how the information from the profiler can be integrated and how it is propagated. These experiments show significant improvement of the retrieved vertical motion. Consequently, the algorithm for the retrieval of the 3-D wind has been modified to combine the UHF information with the bistatic network and its impact is studied for the case of a shallow supercell.
