STUDY OF ENHANCEMENT OF ELECTROMAGNETIC SCATTERING ARISING FROM A HIGH SPEED VEHICLE

SUN BAI-ZHI(Department of Applied Physics, Beijing Institute of Technology, Beijing)  
Calculations of cross sections of EM and EA waves in 8 different incident frequencies and electron densities "on 5 different elevations have been made. The result shows that under normal circumstances, the scattered EM enhancement is greater than that given by Chen. This enhancement of scattered EM waves under special condition of higher frequencies of special zones may be explained by using the influence of the irregular structure of some size in the ionosphere.
