Do police have radar to find marijuana plants?

Answer 1

No. Radar won't work like that. That's the good news. But now for the bad news. Using infrared (IR) equipment, the plants can be seen in broad daylight through "standard" IR viewfinders if the observer knows what to look for - and law enforcement types are good at this. They can cover large areas of territory in a short time from an appropriate air platform to make their surveys. There is more high tech stuff, too. There is heat sensing equipment which can detect the unusual amount of energy it takes to operate an indoor growing operation. Suspect houses can be seen fairly easily with he right kind of optics and using the right kind of sensors, like IR. An aerial spotter can target possible locations and cover large areas in a short time. A "hit" can easily result in a short investigation and surveillance period where a closer look is taken. You may never know you've been checked out and cleared.
