Abstract:

This paper systematically tracked and studied the development of the U.S. long range discrimination radar (LRDR) and expounded on its mission, research and development process, radar system configuration, and derivative development. Based on multi-source open information, after mutual verification and elimination of false information, this paper determined the basic parameters such as the antenna array size, as well as the number and spacing of T/R modules. On this basis, it analyzed the main performance including the operating frequency range, beam scanning coverage, maximum instantaneous bandwidth, detection range, beam width, measurement accuracy, and multi-target capability. This contributes to an in-depth understanding of its capability profile and its role in the U.S. homeland ballistic missile defense operations.

Key words: long range discrimination radar(LRDR), antenna array, subarray suite, detection range, main performance

摘要:

系统性跟踪研究了美国远程识别雷达的发展情况,阐述了其使命任务、研发历程、雷达系统情况及衍生发展情况。基于多源公开信息,经相互印证、去伪存真后,判定雷达天线阵列尺寸、T/R模块数量与间距等基本参数。并以此为基础,对其工作频率范围、波束扫描范围、最大瞬时带宽、作用距离、波束宽度、测量精度、多目标能力等主要性能进行了分析,有助于深入理解其能力剖面及其在美国本土弹道导弹防御作战中的地位与作用。
