总之,红外线传感器是不能提供除目标方位以外的任何信息的,火控计算机也就无法计算导弹的发射包线,更无法靠它发射那些需要机载雷达引导的导弹。不过激光测距仪的工作距离据LO手册说是10km以内,靠它能模糊判断红外制导导弹是否进入射程,但还是无法发射那些需要机载雷达引导的导弹。
在EOS中把雷达打开后,雷达就成了仅仅为EOS辅助测距用的工具,完全不用担心会出现在敌机的雷达告警器上~~
原文如下:
the EOS cannot measure this range and doesn't need it to track a target - an EOS "lock" only provides the angular position of the target. Range measurement is only needed for "LA" - i.e. to determine whether target is within launch parameters of selected missile or for aiming the cannon. For this the WCS uses either the radar as Tito described or(at shorter range) the associated laser range finder
......
the radar can be slaved to it and it is the source providing the range. The radar sends very short, low power output discrete pulses that are so weak that I suppose can be picked up only by the most modern RWR, if possible at all. What is more important in this mode (partialy modeled in LO) is that in case the EOS loses track of the target (for example it goes into a cloud) the radar will automaticaly turn on in full emiting mode and will look at the last known position of the bandit (datalink EOS-radar). Once the EOS picks up the target again the radar goes off again, automaticaly. This how a maximum "stealth" attack is made, I mean with minimum use of the radar.
The EOS indeed has a built-in laser rangefinder which AFAIK works within 10km range (as per MiG-29 combat manual) and in that case the radar goes fully passive. That's the most hidden attack. |
