中文摘要：
为提高无线电波透视技术的探测精度,给出了含入射角度参数的振幅衰减常数表达式。指出在工作频率和媒质参数一定的前提下振幅衰减常数与电磁波入射角度两者满足正弦关系,在0 ~仔/2区间,振幅衰减常数的值随入射角度的增大而增大。采用改进的振幅衰减常数计算得到的数据进行无线电磁波层析成像,结果表明：改进后的振幅衰减常数计算得到的数据层析成像效果显著优于经典振幅衰减常数得到数据的层析成像效果,层析成像剖面图与实测地质剖面吻合较好。证明了采用改进后的振幅衰减常数可以在一定程度上提高无线电波透视的精度
英文摘要：
In order to improve the detection accuracy of the radio wave perspective technology, an expression of the amplitude attenuation constant with incidence angle parameters was provided. The paper pointed out that on the certain premise of the working frequency and Medium parameters, the amplitude attenuation constant and electromagnetic wave could meet the sinusoidal relationship. Within the 0 - ~/2, the value of amplitude attenuation constant would be increased with the incidence angle increased. The data calculated and obtained with the modified amplitude attenuation constant were applied to the tomography of the wireless electromagnetic wave. The results showed that the data tomography results obtained with the modified amplitude attenuation constant would be obviously better than the data tomo- graphy results obtained with the classic amplitude attenuation constant and the section drawings of the tomography and the section drawings of the site measured geology could be well fitted. The modified amplitude attenuation constant could improve the perspective accuracy of the wireless electromagnetic wave in certain degree.
