IBM公司的联邦地区分部揭去了盖在供B-2隐身轰炸机用的APR-50ESM分系统上的几层保密遮纱。在最近的NAECON大会上IBM公司的展品中,展示了APR-50中3种现场可更换装置的照片(见下图),並对系统作了简要介绍。据消息灵通人士说,B-2的每套ESM设备都有若干天线,这些天线馈接到9个能截获各种信号的射频前端上。据报道说,每一前端都调谐到威胁频谱的不同频段上。
IBM’s Federal District Division uncovered several layers of privacy gauntlets on the APR-50ESM subsystem for the B-2 stealth bomber. At the recent NAECON conference, IBM’s exhibit featured photos of the three field-replaceable units in the APR-50 (see below) and gave a brief overview of the system. According to informed sources, each ESM device on the B-2 has several antennas that are fed to nine RF front ends that can intercept various signals. It is reported that each front end is tuned to different frequency bands of the threat spectrum.
