西德西门子公司最近研制出一种新型的机载导航与地形测绘雷达。通常,具有地形测绘功能的机载雷达极其昂贵,并要求具有庞大的天线阵。但是,西门子公司在其Diana方案中所采用的天线不仅为扁平状的,而且体积小。它只要转过一个平面就可以探测地形。新的处理技术能提供具有三个坐标位置的地形测绘。据介绍,这种雷达的性能可与 West Germany Siemens has recently developed a new type of airborne navigation and topography radar. Often, airborne radars with topographic mapping are extremely expensive and require large antenna arrays. However, the antennas used by Siemens in its Diana program are not only flat but also small. It can detect the terrain simply by turning a plane. The new processing technology can provide topographic mapping with three coordinate positions. According to reports, the performance of this radar can be
