ANTENNA AND RECEIVING-SYSTEM NOISE-TEMPERATURE CALCULATION

Abstract

A calculated curve representing the noise temperature of a typical directive antenna in the frequency range 100 to 10,000 mc is presented, together with the method and details of calculation. A methodology for utilizing this antenna noise temperature in calculation of a receiving system noise temperature, from which the total system noise power output and the signal-to noise power ratio may conveniently be computed is given. The use of system noise temperature for comparing the low-noise merit of different systems is discussed. The calculation of received signal power for various types of systems (one-way radio, monostatic and bistatic radar, satellite-reflection communication) is briefly reviewed, to show how the system noise temperature may be used for signal-to-noise ratio calculation.
