具有多台链功能的测距设备实现

摘要

Airborne Equipment has transformed from working for a single ground station to working for multi ground stations. If the slant-range P from 3 ground stations are measured, positioning and navigation can be a- chieved by the P-P-P positioning method. This multi ground stations scanning mechanism will be the developmenttrend of DME. It is shown that this system can realize multi chain work and its performance is reliable.%机载设备已由针对单一地面台工作转变为可针对多地面台工作，如测得距3个地面台的斜距P，利用P—P—P定位方法，可进行定位和导航计算，这种多地面台扫描工作体制将成为DME发展的趋势。结果表明，该系统能够实现多台链工作，性能稳定可靠。
