TL;DR: In this paper, a conceptual design for increasing the output power of an existing X-band planetary radar transmitter from 365 kW to 1 MW was discussed, and the basic transmitter system requirements as dictated by the specifications for the radar are discussed.
Abstract: A proposed conceptual design for increasing the output power of an existing X-band planetary radar transmitter from 365 kW to 1 MW CW is discussed. The basic transmitter system requirements as dictated by the specifications for the radar are discussed. The characteristics and expected performance of the high-power klystron are considered, and the transmitter power amplifier system is discussed. Also discussed is the design of the exciter system. Two alternative feed systems for delivering the 1-MW CW signal to the antenna system are described. The expected performance of the beam supply, heat exchanger, and monitor and control devices is presented. An assessment of the state-of-the-art technology to meet system requirements is given, and possible areas of difficulty are summarized. >
