The non- atmospheric window millimeter wave refers to the atmosphere which weakens the serious millimeter wave's band.
非大气窗口毫米波波段是指大气衰减严重的毫米波波段。
Introduces the working principle of a non-atmospheric window MMW fuze, designing of the system components and choicing of the primary parameters.
文中介绍非大气窗口毫米波引信的工作原理，对系统各部件的设计及参数分析作了详尽的介绍。
But, between in the satellite correspondence, the ground short distance correspondence and the short range radar, the non- atmospheric window has the better secrecy.
但是，在卫星之间的通信、地面近距离通信或近程雷达中，选择非大气窗口具有优良的保密性。

非大气窗口
However, the short-range radar that works on the non-atmospheric window actualizes thebetter characteristics such as the anti-jamming, secrecy and concealment.
近程毫米波雷达恰好利用以上特点，将其工作频率选择在非大气窗口频段，以使得雷达系统可以具有较好的抗干扰能力、保密性，以及隐蔽性等特点。
