抱歉。发现前面个大错。在高度较高的飞机应该是导弹打得更远的。这下面第一句话应该是“在高的高度上对迎头目标”,而不是对高空迎头目标。下边作为相对一句更清楚At low altitude it can fire at ...
其原因大概虽然低空有杂波,雷达效果差,但势能起了作用。

To take one example, the Vympel R-77 has a stated range of 100 km against a head-on target at high altitude, but only 25 km in a stern chase. At low altitude it can fire at head-on targets at 20 km, from which we can guess range in a stern chase is 5 km. (See the above diagram.)
And this is presumably against targets that don't try to evade.
但同篇文指出了对9G机动目标,射程会减少一半以上。这样如果同用AIM120。单纯一方一边倒式射击还是很难做得到。
The improvements planned for, but at the time of writing (2000) cancelled, future versions of AMRAAM include the ability to engage 9G manouevring targets at 30 km, which will let it engage non-agile targets at more than 60 km, which gives a good idea of the range difference depending on type of target. |
