Well, on terrain avoidance, yes, that's fairly simple. What's not simple is avoiding terrain until you reach a certain point, after which you want to collide with the terrain. Identifying that point and autonomously targeting the correct bit of terrain is the problem. There are systems that can detect and locate a signal like an RF jammer, but you have to 1) deploy that system into the area, 2) operate it, 3) maintain it, and 4) protect it. Then to make use of the intelligence it produces you need to have some sort of ordnance or PGM available. That is, you need to dedicate and risk plenty of materiel to take out a simple RF signal broadcaster, with the reward being the use of drones (including the enemy's drones). I don't think your approach is ill-conceived or anything, but the reality for both Ukraine and Russia is that it's really difficult to properly implement that approach. I think the calculation is pretty simple, really: the cost of developing and using a reliable jammer-seeking drone is much higher than the cost of a second jammer.
