What did the sensors say one minute ago? There's no reason this has to be Markovian.
- sandworm101 5y agoBecause, in a jamming/deception scenario, the jammer acting on a sensor won't just introduce a false reading. It will gradually transition from a true to false state in a manner that looks natural. The jammer will attempt to capture the sensor's attention and then shift its attention away from its target ("seduction"). In such cases it is very difficult/impossible to tell which is true based on past readings from the sensor. Google jamming and "capturing the gate" or "doppler pull", techniques specifically to defeat countermeasures dependent on past readings. With two sensors against a jamming target, the sensor with the clearest signal/most confidence is probably the one being most jammed. (IR flares do similar things too.)
