Abstract

Abstract

The results of the integral equation method on the low-frequency ground-wave attenuation factor are inconsistent with other classic algorithms for the homogeneous/inhomogeneous smooth-path models. To solve this problem, a spherical correction factor and an elevation converting technique are introduced to the integral equation method. With these efforts, the results of the improved method are more consistent with other algorithms under the smooth-path conditions. Then, it is used for a real irregular-path model, and the calculated results are compared with the measured ones. It is shown that the proposed method is more suitable for the occasions both on the ground and in the air as the propagation path is long, irregular, and curved.
