本发明与收发天线有关,主要是叙述一同时收发红外辐射和无线电辐射的天线装置。红外探测系统与雷达探测系统已同时用于军事装备中,而且与雷达系统或火力控制系统联合一起用于反飞机或反导弹的防御中。以前需要用两个天线,一个用于红外辐射能,一个用于无线电能。结果由于重量和体积、以及两天线的安装而产生了困难,本发明就是为了克服上述缺点而提供了一个组合的天线。在此装置中,一个红外能的反射器装在雷达天线反射器的后边,雷达天线最好用网状材料制作并固定在红外反射器的前面。在示例图中,所示雷达馈电装置和红外能的第二反射镜装在雷达反射器的前面。外红敏感元件可置于适当位置,例如在相对于红外能反射器开孔后面的一预定位置上。雷达反射器细状材料的尺寸应如此选择,使开孔尺寸此所收发之无线电
The present invention relates to a transmitting and receiving antenna and mainly describes an antenna device that transmits and receives both infrared radiation and radio radiation. Infrared detection systems and radar detection systems have been used in both military equipment and in conjunction with radar systems or fire control systems for anti-aircraft or anti-missile defenses. It used to require two antennas, one for infrared radiation and one for wireless power. As a result of difficulties in weight and volume, as well as the installation of the two antennas, the present invention provides a combined antenna in order to overcome the above drawbacks. In this device, an infrared-capable reflector is mounted behind the radar antenna reflector. The radar antenna is preferably made of mesh material and fixed in front of the infrared reflector. In the example figure, the second reflector of the illustrated radar feeder and infrared energy is mounted in front of the radar reflector. The red-sensitive element can be placed in place, for example at a predetermined position behind the aperture of the infrared energy reflector. The size of the radar reflector thin material should be such that the size of the opening of the radio transceiver
