DJI and third parties sell equipment to track drones and even locate the pilot easily. These are available for a few thousand dollars and were meant to protect airspace such as around an airport but of course they can also be used by militaries to target an enemy. In fact the DJI system [1] will see a drone as soon as its powered on even if it isn't even flying. In the end any drone pilot sending signals can be tracked and the only way around this is to fly a drone completely autonomously with way points and only receive video from it. Some open source firmwares and controllers support such features. [1] https://www.dji.com/ch/mobile/aeroscope https://www.dji.com/ch/mobile/aeroscope
