Paper Abstract

The optimum choice of wavelength for a space-borne imaging radar may be near 1 millimeter. Design calculations of such a near-millimeter radar indicate transmitter peak power Z 26 kW is required for resolution of 1.3 m at a range of 3000 km. The feasibility of developing an amplifier in the optical klystron configuration to meet the source requirements for the radar has been investigated. It was found that a 3-cavity amplifier based on a small period wiggler magnet and incorporating a depressed collector might deliver the required power with efficiency of - 10% and require an electron beam energy of only 315 kV.
