Paper Abstract

Improving performance of beam uplink propagation in the relay mirror system has become a very lively area of scientific research. In recent years, many methods were proposed. But most related researches only concerns power coupling efficiency. We propose that both power coupling efficiency and the non-uniformity of the received beam should be considered. Model of the relay mirror system is established. With this model, damage effect of the system is theoretically analyzed in detail. Performances of uplink propagation with optimizations using different evaluation functions are calculated. Results show that uplink propagation with optimization using power coupling efficiency as the evaluation function can't get the optimal performance. For the 25km-altitude relay mirror system, performance of uplink propagation decreases instead of increases with optimization using power coupling efficiency as the evaluation function. The coming results show that taking the product of power coupling efficiency and the influence factor induced by the non-uniformity of the received beam as the evaluation function of the uplink propagation process is reasonable.
