RCS标准化建议的制定,增强了通信服务的服务效果,能够通过更简单便捷的操作,为用户提供更加丰富多样的通信方式,这也能为跨国家、跨地域的通信创造更好的基础环境,对国家通信业的发展有着重要意义。但是,目前我国在政企客户融合通信方面还处于空白阶段,在建立相关规范标准时,必须加强这方面的考虑,以求RCS业务能够满足政企融合通信的业务需求。文章就是针对RCS业务的应用现状,明确政企融合通信业务对RCS标准化需求,并提出实现政企客户融合通信RCS标准化的主要方向,以供参考。 相似文献

Numerous techniques for measuring monostatic (backscatter) radar cross sections (RCS) are well known, but bistatic RCS measurements are inherently more difficult. In this paper we describe a bistatic RCS measurement technique which circumvents the major obstacles. It uses a variation of the CW "null-balance" approach resulting in rapid measurement times. A network analyzer and process computer were incorporated into an existing image ground plane system to improve the bistatic capability and add flexibility. Several objects were measured and compared with their known bistatic RCS to demonstrate the validity and utility of the technique. 相似文献

The effects of wire antennas carried on aircraft for HF communication on the radar cross section (RCS) at HF frequencies are studied by comparing the RCSs of a strip, a cylinder, and a rod with and without an attached wire. The RCS is found for broadside incidence and for end-on incidence of the plane wave for scatterer lengths from 0.4 to 3.8 wavelengths, typical of aircraft size at HF frequencies. It is shown that the RCS of such fuselage-like targets with a wire antenna is quite different from that of the targets without the wire. For broadside incidence, the wire contributes a sharp peak-and-trough to the RCS are the wire's fundamental resonant frequency. For end-on incidence the wire considerably enhances the RCS at frequencies making its length odd multiples of the quarter-wave 相似文献
