I am a bit confused about this last bit. So Captain Deano is saying once you uncage the missile and the seeker tracks the target perfectly, then the amount of tone drops dramatically? You would think it would be the opposite where the better the track the more insistent the tone. Must have been a technological shortcoming of the seeker?

Some detail from the Navy F5EN manual on "null tone" :

Hello!
About DM mode in the manual does not say anything.
We will seek information on the radar modes.
Thank you.

Would the null tone happen also with newer FM modulated seeker heads or is it only feature in the older AM modulated seekers?

Some docs describing the the seeker modulation:
[ame]http://www.dtic.mil/dtic/tr/fulltext/u2/a286117.pdf[/ame]
http://wiki.scramble.nl/index.php/Si...lated_tracking
http://www.ausairpower.net/TE-Sidewinder-94.html

Basically AM seeker doesn't give any signal to the seeker steering system when it's pointed directly at the target while FM modulate seeker does. To my knowledge the audio tone from a Sidewinder is directly taken from the seeker steering signal. AM modulated missiles should also give different tone than FM modulated missiles besides the null tone difference. AM modulated seeker gives a louder tone when it sees a target while FM modulated gives a louder and higher pitched tone.

Thanks, very interesting. Especially when current doctrine states that you should uncage them before firing to make sure that the missile tracks the target by itself.

I'm here because I saw "CAGE" button on Chuck's F14B guide and had no clue what it was. Now I have a clue but will probably never use it!
