本文对双基地雷达作为远程探测应用的一些主要的特性和性质作了概括叙述。本文着重说明了双基地系统的主要功能,提出了必需处理的各项任务,指出了双基地系统可能达到的探测性能和搜索范围。从性能上看,双基地系统的探测原理比之地面探测器和机载探测器具有更明显的优点。但是,双基地雷达并不是一个能够解决任何要求的完美的雷达系统。所以,必须仔细研究双基地探测器、单基地探测器和网状单基地探测器所特有的要求。 This article provides a general overview of some of the major features and properties of bistatic radars as remote sensing applications. This article highlights the main functions of a bistatic system, presents the tasks that must be addressed, and points out the probing performance and search range that a bistatic system may achieve. From the performance point of view, bistatic system detection principle than the ground detectors and airborne detectors have more obvious advantages. However, bistatic radars are not the perfect radar system that can solve any requirement. Therefore, the unique requirements of bi-base detectors, single-base detectors and meshed single-base detectors must be carefully studied.
