you can also use the strike range option to define a distance within which interceptors will launch to engage, which prevents a no-target intercept from firing the second anything is detected.

You can do this by defining a forbidden zone and marking violators as unfriendly or hostile. You can then create an air intercept mission that launches on either of these postures.

(This also allows you to implement a "two-phase" intercept system. E.g. launch light, cheap interceptors for "unfriendly" contacts that violate the "outer ADIZ" and then launch heavy, sophisticated interceptors for contacts that penetrate the inner zone and are marked hostile.)

Setting strike range is usually very good practice. As for your question, you could also define intercept mission without any targets in list and checkbox "pre-planned only" checked. Then set an event with trigger "Unit enters area", which defines ac types you want to intercept (for example high value like AEW/tankers). When the trigger fires, use Lua UnitX to assign offender as a target to intercept mission using ScenEdit_AssignUnitAsTarget.

Attached is sample scenario targeting Red side AEW and tanker assets, but only those which wander into kill box. You could combine it with other conditions, like no escorts nearby etc.
