Abstract :
Spatial-harmonic magnetrons with cold secondary-emission cathode are promising oscillators for various millimeter wave radar systems. Experience in the development and application of transmitters on the basis of such magnetrons for coherent radar systems is summarized. Design approaches to the development of highly efficient transmitters for the frequencies of 36 GHz and 95 GHz with the power level of 30 kW and 4 kW, respectively, are discussed. Cloud Doppler radar systems based on such transmitters are described as examples of the transmitter applications.
