英国Marconi Avionics公司移动式雷达部最近为英国国家煤炭局研究的矿位雷达,可在2—80米的高度内探测矿位的变化情况。这种装置易于安装,可安在矿仓上方9米高处,不管矿仓深度如何,精度可达±0.75％。据报导这套地面和地下都可使用的探测系统,将于1983年6月底和7月初在英国的采矿设备展览会上展出。这套设备由雷达装置、界面装置和连接电缆组成。这种雷达是J型频带调频连续波雷达,采用先进的微波电路和微信息处理技术,拥有面朝下的截抛物面天线。
Mobile Radar Division, Marconi Avionics UK A mine-level radar, recently researched by the UK National Coal Board, detects changes in ore levels at altitudes of 2-80 meters. This unit is easy to install and can be positioned 9 meters above the top of the silo, with ± 0.75% accuracy, regardless of the depth of the silo. It is reported that this ground-based and underground usable detection system will be exhibited at the mining equipment exhibition in the United Kingdom in late June and early July 1983. This device consists of radar devices, interface devices and connecting cables. This radar is a J-band frequency modulated continuous wave radar that employs advanced microwave circuitry and micro-information processing technology and has a face-down, parabolic-surface antenna.
