法国马赛尔·达索电子有限公司(EMD)第一次在布尔歇展览会上展出了新型主动电磁波自动导引头AD4A,它用于装备新一代空空导弹,拦截高空、低空或超低空飞行的空中目标。AD4A可在发射末段通过比例导航将导弹引向目标,这就使武器系统具有以多枚导弹攻击多个目标的高度机动性。该导引头有一个“固态”发射机,其特点是超高频电路的小型化和信息的数字化处理。 For the first time, France’s Marseille Dassault Electronics Ltd. (EMD) debuted the AD4A, a new active electromagnetic automatic seeker at the Le Bourget exhibition, to equip a new generation of SAMs to intercept high altitude, low altitude or low altitude flights Aerial target. The AD4A can lead missiles to the target at the launch end by means of proportional navigation, which gives the weapon system the high degree of maneuverability to attack multiple targets with multiple missiles. The seeker has a “solid state” transmitter that features miniaturization and digitization of the UHF circuitry.
