摘　　要：针对某机场一二次合装雷达电磁环境影响评价进行探讨,采用模式预测和类比监测。结果证明:①水平方向电场强度随距离变化没有明显变化趋势,近场区低于天线架设高度电场强度能满足5.4V/m的限值要求;②远场区平均功率密度和峰值功率密度分别满足0.08W/m^(2)和80W/m^(2)限值要求。远场区模式预测结果大于监测结果,评价过程采用模式预测方法能保守反映一二次合装雷达电磁环境影响,其评价方法可靠。Exploring the electromagnetic environmental impact assessment of a certain airport’s primary and secondary integrated radar,using mode prediction and analog monitoring.The results show that:①the horizontal electric field intensity does not show a significant change trend with distance,and the electric field intensity in the near field area below the antenna installation height can meet the limit requirement of 5.4V/m;②The average power density and peak power density in the far field meet the limit requirements of 0.08W/m^(2)and 80W/m^(2),respectively.The prediction results of the far-field mode are greater than the monitoring results,and the evaluation process using the mode prediction method can conservatively reflect the electromagnetic environment impact of the primary and secondary integrated radar,and its evaluation method is reliable.
