摘　　要：航天发射场电磁环境日趋复杂和恶劣,电磁辐射及干扰已经成为影响航天发射安全不可忽视的重要因素,为了有效控制和规避电磁干扰对航天发射与测控系统产生的不良影响,需要对航天发射场电磁环境进行仿真研究;通过对比分析理论模型、确定性模型和经验模型等几种常用的电波传播模型,从计算效率、计算准确度以及使用的难易程度出发分析了几种模型对于航天发射场电磁环境仿真的应用;通过适当选择经验模型,能够在获得理想的仿真效果,而且很大程度上缩短了仿真时间、减少对硬件系统的要求;得出可以利用经验模型对航天发射场电磁环境的进行仿真分析;利用经验模型对雷达电磁场覆盖分布情况进行了仿真分析,进一步验证了该模型的适用性。As the electromagnetic environment of aerospace launch sites had become increasingly complex and severe,that the interference of the electromagnetic radiation had become the important ignored factors to influence the safety of the aerospace launch sites.So the simulation calculation for the electromagnetic environment of the aerospace launch sites must be studied.Through the contrast analysis of several common radio waves propagation model,such as the theory model,deterministic model and experience model and so on,the simulation of the electromagnetic environment of aerospace launch sites was analyzed by these several models from the calculation efficiency and accuracy of the calculation and the difficult degree of use.The ideal simulation result could be calculated by the experience model,and the simulation time was shortened.The experience model was more suitable for theoretical analysis of the electromagnetic environment of aerospace launch sites.The radar electromagnetic field distribution was simulated by using the experience model.
