Look, at the T/T method impact point has little importance. The missile attempts to fly on a straight line "connecting" radar to jamming target. The target MUST be somewhere along that line, and radio fuse will find out where smile You need to know target distance only roughly (e.g. from P-18) to determine if the target is in range.

If you mean I87V T/T, I guess that I87V uses some analogue calculator to determine distance using simple trigonometry (altitude / elevation).


T/T method with RAB.OT.VM. arming (just after launch) is good against jamming targets, unless...
... target is flying low, and the armed radio prxy fuse is confused by the signals from the ground.

or

Above Hanoi, the USAF had the nasty habit of laying chaff corridor under the jamming B52's.
If you would launch with T/T RAB.OT.VM, than the missile would pop off when it reaches the chaff corridor.

This is when the I87-T/T comes to play, as it calculates an approximate jamming target distance, so the proxy fuse is not armed, until flies above the chaff corridor.
