Electronic beam squint tracking for land mobile satellite terminals

摘要

Preliminary results from an investigation of the applicability ofnthe electronic beam squint (EBS) tracking technique to land mobilensatellite terminals. Two systems are described, based on the EBSntechnique, which use both conventional waveguide and phased-arrayntechnology. Results are presented covering the error-detectionncapabilities of the systems, along with some operational analysis tonillustrate the dynamic capabilities of the performance of such schemes.nThe systems described are intended for use at L-band and Kun-band. Both techniques appear to offer a simple, and hencencost-effective, alternative to the current terminal arrangements
