摘　　要：为了探索5470-5725MHz频段作为移动接入候选频段的可行性，对该频段气象雷达与WLAN系统的干扰共存问题进行了确定性分析。通过搭建确定性计算仿真模型，确定干扰保护准则，得出在最恶劣情况下的频率距离间隔，为气象雷达与W1.AN之间的共存干扰提供有效的预测方法。To explore the feasibility of 5470-5725 MHz band, which used as mobile access candidate band, the deterministic calculation for the re-search of coexistence interference between meteorological radar system and WIAN system is introduced in this paper. By using interference protection cri- terion, mathematical model is built for deterministic calculation and getting distance separations to provide an effective method of forecasting interference between meteorological radar and WLAN under the worst possible situations. It provides effective prediction method for the research of coexistence inter-ference between meteorological radar system and WIAN system.
