HIGH-RESOLUTION PORTABLE IMPULSE RADAR Pertti Vainikainen*, Martti Tiuri*, Veli Kontra**, Mikko Saarikoski*, Ebbe Nyfors*, ABSTRACT This paper Raimo Salminen** describes an impulse (short pulse) radar with high distance resolution. The radar is intended for subsurface objects or boundaries. The primary application is detection of rot in 1iving trees and power or telephone 1i

X BAND LINEAR ACCELERATOR MAGNETRONS A.M. CRIPPS* AND P.A. JERRAM* ABSTRACT Advances in technology have now made possible the production of portable x-ray machines based on linear accelerators. Operating at X-band these can be broken down into suitcase sized components. The microwave power source has to fit into one of these components but still produce high peak and mean powers. This paper

MILLIMETERWAVE REAL TIME THERR DIMENSIONAL IMAGING. ITS CLUTIER REJECTION PROPERTIES AND- APPLICATION TO THE METALLURGICAL INDUSTRY DING YI-YUAN. LI XIAQ-BO. HUANG SHUN-JI ABSTRACT A new millimeterwave real-time three-dimensional FM-GW imaging radar system has been developed. which is adopted to detect and image the particular objects in a hermetically metallic container. In this paper. we wi

AN 80 W - SOLID-STATE MICROWAVE SOURCE FOR THE EXCITATION OF ELECTRODELESS LAMPS C Ciotti, J T Pinho*, A Neerfries, H J Schmitt ABSTRACT This paper presents a solid-state generator which is able to deliver more than 80 Watts of CW-power at the frequency of 2.45 GHz to an applicator, in order to excite an electrode less plasma lamp. Some of the main features of this generator are the need of a low

THE JET LOWER HYBRID CURRENT DRIVE POWER AND PHASE CONTROL G. Bosia*, C. Gormezano*, J. Jacquinot*, M. Zouhar*, B. Cockerell**, C. Finney**, M. Handel**, S. Sweatman**, A. Thompson** ABSTRACT - the Joint European Torus - is a major experiment aimed at establishing the feasibility of using nuclear fusion as a source of energy in the 21st Century. In a fusion reactor a plasma current of severa

DOPPLER PHENOMENA AT MICRCN(AVE BACKSCATTERING FROM THE SEA SURFACE S. J. Haimov*, A. K. SavchenKo* ABSTRACT In the course of a series of experiments on remote sensing of the sea surface the situation when the general direction of the sea waves propagation was against the wind direction was observed. From the Doppler spectra we found that in such cases the wind influence on the sea surface is

THE APPLICATION OF EXTENSIVE MEASURED DATA ON SCATTERING BY SINGLE HYDROMETEORS TO STUDIES OF MICROWAVE PROPAGATION AND REMOTE SENSING A L Hume and L J Auchterlonie ABSTRACT The results of new extensive measurements on the scattering properties of many simulated hydrometeors are described. These experimental data, having principally for extinction cross-section (ext) apply to particles a range

A HIGH POWER WAVEGUIDE SATELLITE DIPLEXER IN Ku-BAND FOR STATION GROUND Macchiarella** Enzo Cavalieri Abstract d'Oro*, Giuseppe A high power waveguide diplexer has been realized for a combinig transmission system in Ku-band for satellite ground stations. A new design approach for the channel filters is presented; it provides a compact and light weight structure, compatible with the power h

A MOBILE COMPACT 11 GHz MICROWAVE TRANSMITTER for 100 kbitls DIGITAL DATA LINK J. Magnus * ABSTRACT This microwave data link consists of a fixed transceiver station and a mobile part without an active power source. During the short time when both microwave planar antennas are opposite to each other the powered fixed station delivers the RF drive signal for the parametric down-converter working a
