摘要
通过对短波经电离层的E层、F2层传播后的场强仿真计算及最高可用频率(MUF)预测,提出了合理选择车载机动短波发射机的部署位置、工作时机和发射频率等要素,使短波通过E层或F2层反射后,到达预定接收点的场强最大.通过软件仿真预测和试验数据的对比,验证了仿真模型的合理性,为短波发射机的部署方案提供了较为合理的辅助决策建议.
Based on the field strength simulation calculation and maximum usable frequency （MUF） prediction on the short-wave （HF） when propagating through ionosphere E or F2, selections of deployment position, operation time and emission frequency for the vehicle mobile HF transmitter to obtain the maximum field strength at the scheduled receiving spot are proposed when considering the reflection of HF by ionosphere E or F2. Rationality of the simulation model is proved through the comparison between software simulation prediction and test data, which will provide more reasonable assistant decision-making suggestion for the deployment scheme of HF transmitter.
