关于R-27R(E)和SA-10是否会引起导弹发射告警，以及R-27T(E)制导方式的问题

SARH似乎绝大多数需要CW的，是不是AIM7有这个能力不需要CW照射就不清楚了。但是我感觉更像是说那些有CW照射能力的脉冲多普勒雷达也可以提供照射，不是非要加装CW照射器

这里有几个概念误差，在空空导弹领域，中继制导目前还是指本机自射自导，A射B导只有120D才有，目前不是传 ...

你这一说我才想起来远程导弹的燃料问题。。。。。。。。。。。。

我感觉引用资料很不像是这么解释的。

If the pulsed transmission of a high PRF radar is used to
illuminate targets for semiactive missiles to home on, both the
PRF and the duty factor may be made somewhat higher than
they would be for normal searching and tracking

F-16 Block 30/32 - Common engine bay introduced
at Block 30/32 (deliveries from July 1986) to allow fitting of either P&W
F100 PW-220 (Block 32) or GE F110-GE-100 (Block 30) Alternate Fighter Engine.
Other changes include computer memory expansion and seal-bonded fuselage fuel
tanks. First USAF wing to use F-16C/Ds with F110 engines was 86th TFW at
Ramstein AB, Germany, from October 1986. Additions in 1987 included full Level
IV multitarget compatibility with AMRAAM (as Block 30B), voice message unit.
Shrike anti-radiation missiles (from August), crash survivable flight data
recorder and modular common inlet duct allowing full thrust from F110 at low
airspeeds. Software upgraded for full Level IV multitarget compatibility with
AMRAAM early 1988. Industry-sponsored development of radar missile capability
for several European air forces resulted in firing of AIM-7F and AIM-7M missiles
from F-16C in May 1980; capability introduced mid-1991; missiles guided using
pulse Doppler illumination while tracking targets in a high PRF mode of the
AN/APG-68 radar.

那么RWR是以CW脉冲作为SARH正在被制导的信号的话，是否意味着使用HIGH PRF照射来点亮的飞行器不会收到导弹迫近信号？

RWR在何种情况下有何反应与本身设计及设置有关，似乎是很秘密的东西。如果某个RWR可以探测到上面所述的PRF和duty factor的变化，那么就可以设计或者设置成在这种变化发生时发出某种警报。

CW即Continuous Wave、连续波。CW脉冲似乎是一个自相矛盾的词。我没说过脉冲多普勒雷达使用CW进行半主动弹制导。
