前门耦合仿真平台的设计

从天线接收等效电路出发，用专业的电磁电路仿真软件设计并构建一类前门耦合仿真平台．该平台能弥补传统仿真中天线辐照与敏感设备传导之间的割裂，反映耦合过程，为整机电磁兼容与防护提供丰富细节和数据．该类仿真极具开放性，可依据敏感设备特点与候选仿真软件功能，自选相关软件构建该平台．最后以某型接收机为例，用三维电磁仿真软件CSTMWS完成天线辐照，在基于CSTDS和ADS的仿真平台下实现前门耦合模拟，得出接收机内部耦合数据，验证该类平台的实用性．

Design of Simulation Platform for Front-Door Coupling

Starting with receiving antenna equivalent circuit, the simulation platforms for front-door coupling are designed and built with professional electromagnetic and circuit simulation softwares. They compensate for the gap between antenna radiation and sensitive equipment from traditional simulation and perform the real coupling process,offer rich details and data in overall system for EMC and electro- magnetic protection. The simulations truly open for pertinent softwares to build the platforms that are selected by characteristics of sensitive equipments and functions of candidate softwares. Lastly,taking a receiver as an example, software CST MWS completes the antenna radiation and software CST DS accomplishes the other front-door coupling simulation. The validation of their practicability is based on the coupling data of the receiver.
