家园 貌似中国引进的苏27并没有用过原版雷达

原版Su-27配的是N001/N001E,但中国引进的Su-27SK并没有用这个雷达。

前两个批次的可能是"甲虫"雷达N010 Zhuk-27(后来这个雷达的缩水版曾经装备歼8II,没量产的歼8IIM预定的就这款雷达)。

The first of the Zhuk (Beetle) radars was developed for the stillborn mid 1980s MiG-29M/MiG-33 Fulcrum upgrade and production effort. Designated the N010 Zhuk, this was a relatively modern pulse Doppler design modelled on the US APG-65 and APG-68 radars, using a slotted planar array antenna with a 0.68 metre diameter aperture, with an average power rating of 1 kW and peak rating of 5 kW. With the end of the Cold War and Phazotron's emergence as an independent entity in an open market, the effort invested into the Zhuk was exploited to develop a family of radars designed for the MiG-29, Su-27/30 and older Soviet era fighters as upgrades.

The Zhuk-27 was a variant of the baseline N010 but fitted with a much larger 0.98 metre diameter slotted planar array antenna, and possibly an uprated TWT, intended for the Su-27SK Flanker B. Its contemporary was the Zhuk-8P developed for the PLA-AF J-8-II Finback, with a smaller antenna and thus lower range performance.

后来批次的Su-27SK和歼11A使用的是和Su-30MKK相似的N001VE(Su-30MK2用的是N001VEP)。

N001VE和N001VEP都是N001V的缩水版,因为发射功率不足,所以最大探测距离和N001一样是100公里。

.

但Zhuk-27和N001VE/N001VEP都有发射R-77的能力(至少是潜在的能力),都有对地对海扫描的能力,也就是说垂直扫描能达到正负90度(原版N001垂直扫描只有正负55度)。

后来(可能是部分)Su-27SK和歼11A到白俄罗斯588工厂今生了升级,主要就是替换了雷达信号处理机,一般认为在这之后歼11A和Su-27SK正式有了发射R77的能力(但发射模块没有改进,所以最大探测距离仍然是100公里)。
