1993早巴黎国际航展期间,1架经过改装、外形奇特的波音707飞机从以色列直飞巴黎,在航展上仅停留24小时便悄然离去,停留期间杜绝参观者登机。她的出现成了这次航展的热点之一,这就是国际上猜测纷坛的F3——以色列为南美某国研制的新型预警机。 F3预警机之所以令世人注目,最主要的因素是采用了先进的固态相控阵雷达技术。以往的预警机,如美国的E-3A、原苏联的A-50,都是在机背上驮有一付巨大的蘑菇型天线罩,依靠天线的旋转进行扫描。而F3预警机2个很薄的天线罩(长约12米,宽约2为),则是紧紧地贴在前机身两侧,机头还有一个不大不小的半球形天线罩。机头和机身两侧的3个相控阵天线是固定不动的,雷达波束的扫描由计算机控制。
During the Paris International Air Show early in 1993, a converted, fanciful Boeing 707 flew straight from Israel to Paris, quietly leaving for 24 hours at the air show, stopping visitors during boarding. Her appearance has become one of the hot spots in this airshow, which is the international speculation that there are numerous forums F3 - Israel has developed a new AWACS for a country in South America. F3 AWACS so that the world attention, the most important factor is the use of advanced solid-state phased array radar technology. In the past, early warning aircraft such as the E-3A in the United States and the A-50 in the former Soviet Union all boasted a huge mushroom-shaped radome mounted on the back of the aircraft and scanned by rotation of the antenna. The F3 early warning aircraft 2 thin radomes (about 12 meters long, width of 2), it is firmly attached to both sides of the front fuselage, the nose there is a large semi-spherical radome. The three phased array antennas on the nose and the fuselage are stationary and the scanning of the radar beam is computer controlled.
