1986年,在美国《Air Force》杂志上,高级编辑Fdgar Ulsamer建议美国防御界创建一个监视机构,其任务是保持低可观测技术的安全和秘密,并建立一个“红色小组”来预测苏联可能想出的对付美国隐身飞机的各种方法。任何面临这类威胁的国家,最优先考虑的显然是测定隐身战斗机的雷达信号特征。看来有把握推断出,在B-2轰炸机从Palmdale作第一次飞行时,美国以外的无论盟友方还是敌方的个别雷达,总会试图照射这种大型轰炸机。任何熟悉F-117A飞行航线的间谍,均可能试图依靠美国空中交通管制雷达提供的照射能量,以间接的无源法测量其雷达截面积。假设已知这种威胁,问题就分成两个主要方面。必须研制能探测小雷达截面积目
In 1986, senior editor Fdgar Ulsamer suggested in the Air Force magazine that the U.S. defense community should create a surveillance agency with the task of maintaining the safety and secrecy of low observable technologies and establishing a “red team” to predict the Soviet Union may want to Out of the various ways to deal with the United States stealth aircraft. The highest priority for any country facing such threats is obviously the determination of the radar signature of stealth fighter aircraft. It seems safe to conclude that at the time of the first flight of the B-2 bomber from Palmdale, individual radars other than the United States, both ally and enemy, would always attempt to irradiate such large bombers. Any spy who is familiar with the F-117A flight path may try to measure its radar cross-section by indirect passive method, depending on the irradiation energy provided by the United States air traffic control radar. Assuming this threat is known, the problem falls into two main areas. Must be developed to detect small radar cross-section area
