Wait, the passive detector was set up only "a couple kilometers" away from the jet? At that range, I'm not surprised you can detect it up with passive radar. Yo

Wait, the passive detector was set up only "a couple kilometers" away from the jet? At that range, I'm not surprised you can detect it up with passive radar. You could also detect it with an infrared sensor, a pair of binoculars, or even just listening for the jet engine.
- SiempreViernes 7y agoSure, passive radars need a lot of antennas to cover a lot of ground, but the point is they can be made very hard to find since they are passive and that the hardware doesn't cost so much.
- openasocket 7y agoDefinitely, but unless this offers better range than other passive methods (like infrared) this doesn't really change anything.
