Transmitter requirements for modern Doppler weather radars

This paper presents some aspects of a cost-effective design of a Doppler weather radar (DWR) transmitter pulsed power supplies incorporating state-of-the-art technologies. Special emphasis was given to the control system and to the performance of the solid-state power modulator. The new transmitter was compared to a traditional design by a theoretical analysis of the improvement factor limitations of both systems. Because it is difficult to find published papers which describe the application of the well-known MTI improvement factor derivation procedure on a real-word system, the authors have described this method to a greater extent
