Abstract

There is an increasing demand for a highly accurate weather system on the runway for early detection and warning of severe weather phenomena. Due to the high performances of a phased array radar system in terms of time-resolution and elevation-resolution, an already existing fast-rotating phased array radar, 60 RPM, is studied to find the possibility to implement a second processing chain, dedicated to weather applications. Thus, the research in this project is carried out for signal processing algorithms for beamforming, target mask, and Doppler aliasing correction, meant to reconstruct 3D Doppler maps at high estimation accuracy of precipitation profiles, and determine this radar potential as weather radar.
