Sorry to disagree, here’s my radio perspective:
Radar has a carrier frequency yes, like any radio. And it is not in the 2.4GHz or 5.8GHz ISM bands where most drones operate. However, radar works by sending a very short high-power pulses towards a target, the radio wave bounces back and is received by the Radar receiver. The powers are very high, as you can imagine the received signal is very weak. We are talking often several megawatts peak power.
Radio receivers are not perfect, they have components which provide selectivity, the ability for your radio to receiver the signal you want and reject all others at other carrier frequencies. However, if the victim (the drone) is physically close to the aggressor (the Radar) the received out-of-band power will be very high, this will probably overload the drone’s radio front-end.
You could see loss of control of the drone as it would be deaf to your commands. It could lose GPS lock as GPS receivers are extremely sensitive (they have to decode signals transmitted 12,400 miles away). You could also experience loss of the camera image, or at least banding or interference on the display.
Military receivers are hardened to some extent, but commercial equipment such as a mass produced drone, would be quite vulnerable I think.
If you really want to fly there, perhaps start to fly in the Radar beam a long way off, see how it goes, and fly slowly towards the tower to determine any problems. But you won’t know if the Radar is on or off, or they may turn it on mid-flight. These radars are not safe to humans either - stay safe.
