Home On Jam

Anti-radiation seekers home in on the radiated energy of a target. These seekers also make great validators, allowing the missile to discriminate between a ship and a simple decoy like chaff by checking for radio emissions

HOJ is a subset of ARAD seeker, costing 0.5pt when a ARAD seeker is set to jamming signals only mode. When operating in this mode, the seeker only looks for radar jamming signal within its cone, and steers the missile towards the target. It should be noted that the HOJ seeker is not limited to 3km, and can home to the direction of offending jammer from afar. HOJ seekers do not home on comms or electro-optical jamming.

HOJ has 30 seconds of "validator memory", which means that as long as a track has been validated by the seeker once and the primary seeker can still see the target, it will stay valid for at least 30 seconds even if it no longer seen by the HOJ validator. In addition, HOJ validator's memory will consider any target within 5 degrees of the jamming source to be valid. Note that for the target to be valid the primary also has to see the target!
