Digital Signal Processing for a Ka Band Satellite Beacon Receiver / Radiometer

Abstract

This paper describes the Digital Signal Processing (DSP) techniques required to ensure that a Ka band Satellite Beacon Receiver/Radiometer remains locked to the satellite beacon and provide a measure of both the sky noise and the attenuation caused by rain to satellite signals. To enable the receiver to stay locked to satellite beacon signals with received power levels between -110 dBm and -170 dBm, a receiver with an ultra low phase noise, an absence of spurious signals and using advanced Digital Signal Processing (DSP) techniques is required.
