Abstract
Techniques are disclosed for determining the presence of pulse jams in an identification friend or foe (IFF) system. In an embodiment, a plurality of jamming pulse rates are determined. Each of the plurality of jamming pulse rates is a count of jamming pulses entering the IFF system during a corresponding integration period. Each of the plurality of jamming pulse rates is a count of jamming pulses associated with non-valid signals entering the IFF system. An average jamming pulse rate is computed based on the plurality of jamming pulse rates. The average jamming pulse rate is then compared against a pulse jam threshold to determine whether a pulse jam is present (or not present) in the IFF system.
