近些年来,在移动体无线电通信及其测位方面,采用漏泄电缆这一技术得到了迅速的进展。为了适应所提出的任务,曾研制出在外导体上开有周期小槽孔的中等尺寸漏泄电缆。在研制漏泄电缆时,提出了包括电气特性在内的综合性要求:特性阻抗Z_B、衰减常数α、表征电缆漏泄特性的专门功能参数——沿电缆长度方向上平均耦合损耗(Ac)。漏泄电缆的特性阻抗和衰减常数,其物理意义与射频电缆相同。耦合损耗系表明通过电缆截面的功率与一定类型和一定方向的天线所接收的功率之比。但这时电缆的截面
In recent years, there has been rapid progress in using leaky cables in mobile radiocommunication and its positioning. In order to adapt to the proposed task, has developed a medium-sized leaky cable with periodic small slots on the outer conductor. In the development of the leaky cable, the comprehensive requirements including the electrical characteristics were proposed: the characteristic impedance Z_B, the attenuation constant α, the special functional parameter characterizing the cable leakage characteristic - the average coupling loss (Ac) along the length of the cable. The characteristic impedance and attenuation constant of the leaky cable have the same physical meaning as the RF cable. Coupling loss is the ratio of the power received through the cable cross section to the power received by an antenna of a given type and orientation. But this time the cross section of the cable
