二战之初,轰炸机曾被英国人视为能够轻松重创敌方的战略武器,但皇家空军最初所开展的昼间空袭行动证明,轰炸机远比预想中的脆弱,如果不借助夜幕的掩护,其损失将是难以承受的。然而在漆黑的夜空中,成功穿越敌方领空并准确找到攻击目标十分困难,德国空军为此研发出多种无线电导航波束,英国空军也研制出了一种基于全新概念的导航系统。令人担忧的是,在第二次深入德国领空进行的试验飞行中,英国一架装有新导航仪的轰炸机失踪。为防止敌人发现其中的秘密,英国人紧急启动了一系列欺骗措施,双方电子专家间的一场较量拉开帷幕。 At the beginning of World War II, the bomber was seen by the British as a strategic weapon that could easily infringe the enemy. However, the initial air raid conducted by the RAF proves that the bomber was far more vulnerable than expected. Without the help of night cover, its loss Will be unbearable. However, in the dark night sky, it has been very difficult to successfully cross the enemy’s airspace and accurately find the target of attack. The German Air Force has developed various radionavigation beams for this purpose. The British Air Force has also developed a navigation system based on a completely new concept. Worryingly, a bombing aircraft carrying a new navigator in the United Kingdom disappeared during the second experimental flight into German airspace. To prevent the enemy from discovering the secrets, the British launched an emergency series of deception measures and a contest between electronic experts of both sides kicked off.
