You want a hack that will make the antenna follow a target track without actually locking on? As a bomber pilot, not sure but is this to ensure you stay in contact using something like TWS and you not having to control the tilt etc?
No offence, but online couldn't this be viewed as a cheat? I may have the wrong end of the stick, so don't be nasty :)
I think what GG is saying, you may be able to control the tilt etc, but would have no feedback as to if the radar had tilted too much/little to remain in contact. If you could somehow get feedback as to the position of the contact within the current cone of radar, then it would be fairly easy. Is this a parameter that is available?
