摘要 指出平面1维近似不符合在远场处微波单位面积能流与传输距离平方成反比的规律。给出了柬流1维近似下微波大气传输的基本方程组。详细研究了微波电离大气的特性和相似律。估计了平面1维近似下和束流1维近似下的尾蚀,指出当无量纲电离电子数不太小时,两者可能有很大差别。 That the disconsistency between the plane one-dimension assumption and the law that the microwave energy flux per unit area is inversely proportional to the square of the propagation distance is pointed out. The fundamental equations of the HPM propagation in the atmosphere under the beam flux one-dimension assumption are given. The characteristics and scaling laws of the ionization atmosphere are studied in detail. When n/ne is not too small, the great difference on the tail-erosion between the plane one-dimension and the beam one-dimension assumptions is presented.
