WARLOC: a high-power millimeter-wave radar

Abstract

A high-power, coherent, W-band (94 GHz) millimeter-wave radar has been developed at the Naval Research Laboratory. The radar employs a 100 kW peak power, 10 kW average power gyroklystron as the final power amplifier, an overmoded transmission line system, and a quasioptical duplexer, together with a 6 foot Cassegrain antenna, a four-channel receiver, and state-of-the-art signal processing. Developed as a research radar for the investigation of tactical Navy radar applications in the millimeter wave band, additional radar measurement studies include cloud physics, propagation, and forward and backscatter studies.
