The active jammer will then work to reduce the tracking range of enemy radars and degrade the
performance of incoming radar-guided missiles. The player's use of such active ECM may come at a
price, however. The ECM may interfere with the player's own radar-guided missiles during or after
launch, hostile radars experiencing reduced tracking range may nevertheless enjoy increased
detection range, and hostile missiles may see active ECM as a beacon, and pursue it in a secondary
"Home On Jam" (HOJ) mode. For the best defense against missiles, active ECM is best combined
together with passive jamming (chaff) and perpendicular ("beaming") maneuvers at low altitude.
