Quck Reaction Corp. will develop a precise radar reflectometer, capable of searching for the 100,000,000 land mines that are buried throughout the world, which are responsible for maiming or killing thousands of innocent people annually. This reflectometer will measure very small changes in reflection which are caused by the presence of land mines. To locate land mines, the search area is illuminated by an array of small foot print collimated antennas. The ground caused reflected signal in each antenna beam is measured and continuously cancelled by an active loop, resulting in a precise vector measurement in each antenna caused only by the ground reflection. It is the difference between adjacent beam's ground reflection vectors that provides detection. This approach will improve detection and estimates of target location and size.

Quck Reaction Corp.将开发一种精确的雷达反射仪，能够搜索埋在世界各地的1亿枚地雷，这些地雷每年导致数千名无辜者致残或死亡。该反射仪将测量因地雷的存在而引起的反射的微小变化。为了定位地雷，搜索区域由一组小型足迹准直天线照明。每个天线波束中的地面反射信号被测量，并由有源环路连续抵消，从而导致每个天线中仅由地面反射引起的精确矢量测量。提供探测的是相邻波束的地面反射矢量之间的差异。这种方法将改进对目标位置和大小的检测和估计。
