本述评概括了用于远程检测的双基地雷达的某些主要性能和特性,突出了主要的系统功能,指出了所需的处理任务。还用一个双基地系统作为例子来说明可达到的检测性能和监视覆盖范围。双基地的检测原理对面基(地面或航载)和机载探测器都能提供良好的性能优势。但双基地雷达并不对于每种技术要求都是完美的系统方案,因此必须针对各个特殊的技术要求仔细地研究双基地、单基地和组网的单基地等各种探测器方案。
This review summarizes some of the key features and capabilities of bistatic radars used for remote sensing, highlighting key system functions and pointing out the required processing tasks. A two-base system is also used as an example to illustrate the achievable detection performance and monitoring coverage. Bistatic detection principle provides good performance advantages for surface-based (ground or airborne) and airborne detectors. However, bistatic radars are not the perfect system solution for every technical requirement. Therefore, various detector schemes such as bistatic, single base and networked single base must be carefully studied for each particular technical requirement.
