美机与苏机雷达俯仰角的区别

LOCKON里只有锁定警告和导弹迫近警告吧？其中敌机锁定你和敌主动雷达制导的导弹锁定你都可以触发锁定警告。
发射警告是啥呢？

LOCKON_FC2_Flight_Manual_EN 214页

If a missile launch is detected, an audio launch warning will be heard. It will
repeat itself every 15 seconds until the threat is gone.

STT模式为雷达所有能量连续脉冲目标 怎么可能会没有动静 虽然用STT发射120不能体现出TWS的优势 但是实战中 ...

STT下发射120敌机只会收到雷达锁定告警，不会有导弹发射告警。雷达只把目标的位置、速度和飞行方向通过数据链发给AIM-120（数据的更新频率不是很快），然后由120的惯导系统引导导弹飞往目标。对方的雷达告警器无法探测到我机雷达的频率和能量变化，因此对方不会收到导弹发射告警~~~The AIM-120's Inertial Guidance System gets information about the target right before it comes off the rail so that it can perform a completely autonomous intercept on a target whose velocity vector fairly nearly constant. If the shooter aircraft's radar shows no appreciable update in the target's course before the AIM-120 goes active, it may end up sending very few course corrections to the missile. However, if the shooter aircraft's radar sees that the target is constantly changing course and/or speed and/or altitude, it's going to have to send many more mid course updates to the AIM-120 before it goes active. It may still be difficult to detect the datalink transmissions in this case.


。。。。。。。。。

MORE INFO:

The launch aircraft sends data to the missile just prior to launch, including the location, speed, and direction of the target aircraft. The AIM-120 uses this data to fly an intercept course using its onboard inertial navigation system (INS). The launch aircraft typically provides this data from its radar, but an infrared search and tracking system (IRST) or data link from another aircraft can also provide it.

The AIM-120 receives periodic updates about the speed and direction of the target from the launch aircraft so that it can adjust its course to reach a self-homing distance, controlling its flight with four movable tail fins. Once at self-homing distance, the AIM-120 can lock onto the target, turn on its active radar seeker, and use its autonomous self-guidance to reach the target. Upon intercept, an active-radar proximity fuse detonates the 40-pound high-explosive warhead to destroy the target.

雷达扫描时飞机俯仰不会影响雷达天线俯仰，俄美的雷达天线这个物体在扫描时总是相对于水平面俯仰稳定。
飞机雷达天线俯仰范围一般是相对于飞机+-60度。

俄国雷达有滚转轴，俄国的雷达天线这个物体在扫描时总是相对于水平面滚转稳定。
俄国飞机雷达的滚转范围一般是相对于飞机+-120度。
美国飞机雷达不能滚转。通过调整摇摆和俯仰来保证扫描相对于水平面的滚转稳定。
美国飞机雷达滚转没有角度限制。

Don't get me wrong. 相对于水平面稳定与稳定在水平面是不同的。
雷达STT/锁定时将在机械允许范围内总是指向目标。
这里提到的是机械扫描多普勒雷达。
