Great one!!Semi active guided missiles require continuous illumination and missile follows the radio waves reflected by target so Target’s EW can easily detect those missiles with “lock” signal.
If the missile is Rf guided active homing, then The missile’s radar emits the continuous waves to target and same missile receives the reflected waves from target. Continuous illumination is not needed in those missiles but RWR can detect them with the waves emited by missile itself.
If the missile is Command guided, the search radar track the target and a seperate radar track the missile itself. The fire control computer calculates the interception point in accordance to datas received by both radars. The missile is steered to intercept with target by same seperate radar. This is the most sneaky way of striking high value targets because The target will realize a radar (If not working on passive mode) tracking itself but never know a missile approaching to him. That is the method developed to overcome RWR but, The ultraviolet signatures of coming missile can be detected by MWR. The latest generation missiles have smokeless propulsion with less heating signature on terminal phase with stopping rocket motor not to burn fuel in this phase so the pilot will just have a few second to realize He is going to be wasted in a short time. Hisar-IIR is the most effective way of killing enemy aircrafts thanks to command-guided method on midcourse and IIR guidance ın terminal phase but IIR sensors bring some limitations on surface to air missiles. They are good but not perfect on naval applications because of being effected by bad weather conditions and foggy environment. Same for land based variants on regions having rainy and foggy climate conditions. Their ranges are not long enough against active homing missiles so Hisar-O will be revealed in two different variant. IIR and Rf.
another problem with those missiles that need illumination radar, those radars will be the first target as soon as they lock on... once you hit the radar with anti radiation missiles like harpy fast, you also kill the missiles itself..
