美空军将在阿拉斯加投入比预算高一倍左右的费用以建立两个超视距后向散射雷达扇形区,其部分原因是属于环境方面的因素即是需要在冻土层上建立大型天线。GE公司是所有超视距后向散射系统的主承包商。在美国空军电子系统部下属的超视距后向散射规划办公室负责阿拉斯加雷达系统的李·切斯黑尔中校说:在早期规划阶段空军的估计是,场地准备和建造费用要比在缅因 The U.S. Air Force will spend about twice as much on budget in Alaska to create two over-the-horizon backscatter radar sectors, due in part to the environmental considerations of the need to build large antennas on the frozen ground.
