12 GHz site and orbital diversity - Measurements and predictions
Abstract
Radar simulations and dual SIRIO-OTS satellite beacon measurements have yielded site diversity and orbital diversity results which indicate that the former reduces power margins by 60 percent for a station separation of 10 km, or by 80 percent when they are 20 km apart, while the latter reduces the power margin by only as much as 40 percent. Both types of diversity may nevertheless have their appropriate application; orbital diversity can moderately reduce the power margin of many sites through spare-channel reuse. A model for the accurate prediction of both site and orbital diversity gains is presented.
