一、AIM-7麻雀导弹麻雀导弹计划由美海军航空局投资,开始于1946年。1951年斯派里公司获得导弹的全面工程研制合同,当时命名为 XAAM-N-2麻雀Ⅰ。麻雀Ⅰ是雷达驾束制导式导弹,与机载雷达随同,没有得到广泛实际应用。麻雀Ⅱ(XAAM-N-3)采用全主动雷达制导。按照当时的电子技术,要把主动雷达寻的头放到20.32厘米直径的弹壳里是绝对难以实现的,因而被放弃了。1955年雷锡恩公司 First, the AIM-7 Sparrow Missile Sparrow missile program is funded by the U.S. Navy Aviation Authority and began in 1946. In 1951, SPELLER received a contract for the full engineering of missiles, which was then named XAAM-N-2 Sparrow. Sparrow I is a radar-led guided missile, along with airborne radar, has not been widely practically used. Sparrow II (XAAM-N-3) uses fully active radar guidance. According to the electronic technology at that time, it was absolutely hard to put an active radar seeker into a 20.32-centimeter-diameter cartridge and was dropped. 1955 Raytheon Corporation
