So called 'passive' radars. FM radio, cell towers, and also dvb-t. Wonderful tech. Is there an actual (not toy or PoC) operational system deployed anywhere?

- sobriquet9 5y agoThere is no way to know. An actual operational system deployed anywhere would be impossible to detect. It does not transmit anything, and can use existing antennas for receiving the signals. Can be as simple as software update.
