用低功率激光束取代习用的微波辐射的雷达系统,已探测到能对低空飞行产生危害的难于察看的物体。在试验飞行中,已探测到习用的机载雷达装置所不能探测的物体,包括陆军的野战电线。联合技术研究中心为陆军的电子司令部研制的激光系统,称作激光障碍和地形闪避警报系统。 Radar systems that replace conventional microwave radiation with low-power laser beams have detected unobtrusive objects that can be harmful to low-level flight. During the pilot flight, objects that could not be detected by conventional airborne radar installations were detected, including Army field cables. The United Technologies Research Center for the Army’s electronic command developed laser system, known as laser obstacles and terrain dodge alarm system.
