摘要: AbstractAn L-band radar wind profiler was established at National Atmospheric Research Laboratory, Gadanki, India (13.5°N, 79.2°E), to provide continuous high-resolution measurements in the lower atmosphere. This system utilizes a fully active array and passive beam-forming network. It operates 1280 MHz with peak output power of 1.2 kW. The comprises 16 × microstrip patch antenna elements fed by dedicated solid-state transceiver modules. A 2D modified Butler network is employed feed array. combination results enhanced signal-to-noise ratio simple beam steering. also direct intermediate frequency (IF) digital receiver pulse compression scheme, which result more flexibility height coverage. scientific objectives this are study atmospheric boundary layer dynamics precipitation. Observations made have b...
