Numerical Solution for Received Power Estimation in a Wave Propagation — A Case of Ground Based C-band SAR Test

Despite the long history and wide application of computer simulation on wave propagation, it is found interesting that study on numerical solution to estimate the amount of received power at the receiving antenna is limited. While, in preparing a radio transmission system, including a SAR system, the estimation of received power is crucial. A good estimation on received power shall reduce the probability of an on-field failure. This article is mainly aimed to addresses several aspects in concepting the solution to this issue. In particular, a ground-based C-band SAR test scenario using a 5.3 GHz carrier and our newly designed transmitting and receiving antennas has been taken as a case as the simulation model.
