摘要
在河南省新乡地区进行了准平坦地形条件下４５０ＭＨＺ频段干扰场强的测试，给出了实测干扰场强与有关预测模式的比较结果，并给出了距离与５０％、１０％和１％时间概率所超过干扰场强的统计表达式。
In searching of the predicated model of interference field strength applicable of the terrain conditions, of China, a test of interference field strength at 450MHz for the quasi-smooth terrain conditions was carried out in october, 1992 in Xinxiang, Henan. A simulated signal source as the interference source, the test vehicular platform was moving in the circumference of 50km, the test was completed along the roads in five directions of east' west' south' north and north -east respectively within the distance of 85km. The measured results of the interference field strength were compared with several well- known predicated models of extra-short wave propagation, and the statistical expressions of distance and measured field strength exceeded for the time probability of 50%, 10% and 1 %, were also given.
