SELECTED PROBLEMS IN COMPUTERIZED WIDEBAND SCATTERING MEASUREMENTS Hans-Jiirgen Meckelburg, Klaus Matkey and Dietmar Lipka* ABSTRACT One of the major problems in scattering measurements are unwanted scattering contributions like environmental reflections and antenna cross-talk often summarized as clutter. In computerized microwave network analysis a subtraction method can be applied to elimina

DESIGN AND OPERATION OF A WIDEBAND RCS MEASUREMENT SYSTEM P J BALDWIN*, P BORDER*, S V DAVIS**, A G PAYNE**, S P ROWE** ABSTRACT This paper concerns an experimental Radar Cross Section (RCS) measuring equipment intended for use against a wide variety Of full scale radar targets. A single frequency tracking radar, operating on a conscan principle, acquires the target and provides accurate

POLARIMETRIC WATERWAYS S. Haykin*, ABSTRACT RADAR FOR PRECISE NAVIGATION ALONG CONFINED A. Macikunas*, and T. Greenlay* The paper describes a new radar concept, referred to as polarimetric radar, for providing precise navigation along a confined waterway. The system relies on polarization as the radar discriminant. A passive radar reflector that converts polarization of the incident radar

POSE I OON RADAR AL T I METER CHARACTER I ST I CS AND PERFORMANCES Nadia KAROUCHE - Luc LAPIERRE - Philippe RAIZONVILLE - Christian BOSCHET ABSTRACT The spaceborn altimeter descibed in this paper will provide accurate altitude measurements of the sea surface and will determine with other instruments the general c irculat ion of the oceans. Thi Ku band radar s altimeter is under study at C

A COHERENT, FREQUENCY AGILE 94 GHZ RADAR WITH DUAL POLARISATION CAPABILITY Alfred Plattner* Abstract A coherent, frequency agile 94 GHz radar has been built. This radar includes features like pulse-to-pulse frequency agili ty within a 400 MHz bandwidth, wide PRF-range from 150 kHz with fixed and staggered PRF. The polarisation of the transmitter is switchable from pulse to pulse either from RHC to

GaAs MONOLITHIC MICROWAVE INTEGRATED CIRCUITS W. R. Wisseman ABSTRACT Rapid advances have been made in GaAs monolithic microwave integrated circuits (MMICs) during the past several years. This paper will review the status of monolithic technology, focusing on power amplifier development and the extension of amplifier operation to frequencies of 20 GHz and above.

GaAs MMICs FOR MASS PRODUCTION 12 GHz TV DOWNCONVERTERS C. KERMARREC* ABSTRACT GaAs MMICs are contenders to lower the price mass-production way of 12 GHz DBS downconverters. and to open the LEP** and other laboratories have demonstrated the feasibility of multichip or single chip DBS receivers. This paper shows that it is now the time to improve the design for reducing circuit size, to fix a te

THE DIELECTRIC RESONATORS AND THEIR APPLICATIONS IN MICROWAVE CIRCUITS Pierre GUILLON ABSTRACT This paper reviews the different techniques available for the electromagnetic and electrical analysis of dielectric resonators parameters, and present some applications of these dielectric resonators in microwave passive (filters) and active (oscillators) components. The use of the dielectric re
