A novel W-band fully coherent solid-state radar transceiver

A W-band fully coherent pulse Doppler radar was developed in the South West Institute of Electronic Technology (SWIET). The fully solid-state radar transceiver is characterized by a coherent frequency source using IMPATT diode /spl times/ 15 frequency multiplier, 4-stages of IMPATT diode inject-locked W-band pulse power amplifiers, millimeter wave power combiner, and low noise heterodyne receiver with one frequency down conversion. It has not only good electrical performance, but also other merits such as reduced system construction, good electromagnetic compatibility and high reliability.
