Iris - t

I’ve noticed the IRIS-T radar is able to track through solid objects such as building, hills, etc…
I’ve played it myself, and I can park in right in between large buildings where the radar is completely blocked 360 degreesl and still I can still easily track and fire on targets…
Same way on the other end… I’ll be landing my helo at a base which is completely blocked by large hills, and still the IRIS-T is able to track and kill me despite radar not being able to penetrate hundreds of feet of earth…

Do we play the same IRIS-T?
