[Milsurplus] FM vs AM in aircraft

[Jack Antonio]

I have heard that one of the issues with FM in military aircraft is
the unpredictable nature of phase shifts due to doppler, at high speeds
or in manuevering.

The question is:

Is there any documentation anywhere discussing this?

My searches just return discussions of capture effect.
It seems to me that somewhere, someone would have researched
this.

Thanks
