Tracking receiver design for the electronic beam squint tracking system in the mobile environment

The authors investigate the beam squint technique from the viewpoint of the tracking receiver in a mobile satellite environment, together with the more general problems experienced by tracking receivers in this situation. This technique is detailed with particular reference to the design and characterization of an optimum tracking receiver, and the new problems which the system poses in this area. The system is described with an identification of the factors in existing receivers which limit the performance of the electronic tracking technique. Using a computer simulation, a fundamental understanding of the physical processes involved is presented and some comprehensive experimental results are included to validate the conclusions and proposed solutions. The techniques described may also be applied to conventional tracking systems, with a useful improvement in performance
