与西方的同类型号相比,苏联的航空电子设备一般几乎要大50％,其原因之一是它们保留了真空管和混合工艺。苏联的机载雷达已从E波段移到了I/J波段,部分原因是为了减小尺寸。苏联的雷达功率常常比西方的大2到10倍,因此作用距离远,抗干扰能力强。自1960年以来,若干雷达已具有电子抗干扰能力,现在苏联的雷达是仿制美国F-4和F—14的雷达。虽然在伊朗的帮助下苏联采用了美国的雷达技术,但南朝鲜航空公司的两架飞机进入其领空证明,苏联在截获 One of the reasons why the Soviet avionics are generally 50% larger than similar models in the West is that they retain the vacuum tube and the mixing process. The Soviet airborne radar has moved from the E-band to the I / J band in part because of the reduction in size. The Soviet Union’s radar power is often 2 to 10 times larger than in the West, so the range is far and the anti-interference ability is strong. Since 1960, several radars already have electronic anti-jamming capabilities. Now the Soviet radar is a replica of the US F-4 and F-14 radars. Although the Soviet Union adopted the radar technology of the United States with the help of Iran, the entry of two of South Korea’s airlines into its airspace proves that the Soviet Union intercepted
