Shouldn't it be the other way around?

180 degrees should be the engagement envelope for a head on engagement, while 0 degrees should be the engagement envelope for a tail chase.


The engagement envelope for a head on engagement for a AAM should be the highest value, while the engagement envelope for a tail chase engagement should be the lowest value.

Actually I take this back, regarding the 0 degrees thing.

For two reasons

First, is that typically 0 degrees refers to head on

Second, is after talking to some others, this might not represent a simple kinematic plot/graph.

I think that perhaps the azimuth readings such as 180 degrees might refer to the flight direction of the target relative to the launcher. So 180 degrees is the target head on, where the missile range would be at maximum.

That's initially what I thought on the last page (post 928), but I have reason to believe it isn't the case.

As I wrote above, 0 degrees typically indicates "head on" in most aviation headings.

Additionally, this plot may not represent simple "engagement range" or kinematic engagement envelope alone.

Well, perhaps other more knowledgeable folks might read it differently, but to my simpler mind it does seem like 180 degrees head-on, 0 degrees tail chase (so perhaps i was wrong about firing to the rear theory). So ranges look something like around ~270-280km head-on, ~120-125km or so tail-on for PL-16, ~180-190/100 for PL-15 and ~55-60/25-30 for PL-12.

But again, others might have a different/better interpretation.

Hmm try thinking how the numbers could make sense if it is 0 degrees head on, and 180 degrees tail (rather than tail chase).

There is a potential reason to the madness.

Maybe 0 degrees means that the target is moving away from the missile at launch (a chase vector).
And 180 degrees is the opposite (the target is moving towards the missile).
