摘要
根据SAR实时传输要求,从实际数据传输速率、成本等方面对我国现行的3种3G标准进行了对比分析,指出3种标准各有优缺点,TD的理论传输速率不如CDMA2000和WCDMA,但实际的应用中并不一定落后,而WCD-MA需要重新建立接入网,升级成本高,TD和CDMA2000则最大限度利用了已成熟的技术,演进成本低。要实现SAR图像数据的3G实时传输,要根据具体雷达数据量、SAR系统所处位置及各网络提供商的传输能力来定。
In order to sufficiently make full use of SAR system in military domains as detecting and guiding, and in civil as- pect as mapping, through studying current 3G communication standards in China, taking the model SAR images data as an example ,we have analyzed the feasibility and efficacy of real-time transmission analysis of SAR images based on 3G commu- nication system.
