MULTI STATIC CW-DOPPLERRADAR AT 35 GHz WITH LATERAL RESOLUTION FOR SHORT- RANGE-APPLICATIONS J. Detlefsen. ABSTRACT Lateral resolution without scanning the antenna is achieved by a new method, which uses several homodyne receivers positionned along a linear aperture in order to evaluate the incident angles of the incoming wavefronts. The sampled values of the field distribution along the ap

AN AUXILIARY PASSIVE MICROWAVE NAVIGATION SYSTEM A. APPRIOU .. , B. VAIZAN , F. LE CHEVALIER . ABSTRACT This paper describes an original passive microwave system which, on the basis of further informations delivered by the sensors of the main navigation system, performs the two following functions: altimeter and nGvigation updating (for low-cost inertial systems). Furthermore, simulation

3mm Continuous Comparision Radiometer C. R. Predmore, N. R. Erickson, G. R. Huguenin, and P. F. Goldsmith * Abstract A 3mm wavelength dual-beam radiometer utilizing quasi-optics and Schottky diode mixers has been developed at the Five College Radio Astronomy Observatory. This cryogenic system eliminates ~hel1ee,d for mechanical beam or load switching, continuously',subracting ouJ: ' atlOsp

LOW NOISE RECEIVER CONCEPTS FOR 12 GHZ TV SAT RECEIVERS R. Maurer and H.P. Petry * ABSTRACT Design considerations for receiver concepts in the 12 GHz region concerning the cooperation of linear and nonlinear units are given. Noise figures are shown to be dependent on system arrangement and modes of operation. Two examples describe the properties of realized prototype receivers.

The paper gives some background, compares sensitivity using

SATELLITE TV DISTRIBUTION SYSTEM "MOSCOW" V. M. Dorofeev, L. J. Kantor. ~~2!~~Q! The 4 GHz television distribution system called Moskva is developed in the USSR in addition to the presently operating TV distribution system. The system described is a supplementary one to those which operate in the 4 GHz band allocated for the fixed services as well as in other frequency bands.
