    Ha amit írsz, korrekt, akkor gyakorlatilag a teljes európai Eurocanard-család, a teljes F-15, F-16, F/A-18, Szu-27 és folyományai, MiG-29 és folyományai gépeket használó országok egy elavult rendszert üzemeltetnek, amely a modern légvédelmi rendszerekkel védett A2/AD rendszeren úgy fent akadnak, mint légy a szúnyoghálón.

    TRIANGULATION
    3-57. The triangulation process provides the Patriot system with the capability to counter ECM. There may be occasions when the jamming source is able to deny range data to the fire unit. When this occurs, that track is reported to the ICC as a strobe with azimuth and elevation. This strobe will also be detected by other fire units within the battalion and reported to the ICC, provided there is overlapping coverage. The ICC then performs a strobe correlation process, called triangulation, to determine the target's range and provides this information to the reporting fire units. The triangulation process is performed with data from adjacent Patriot battalions and subordinate Patriot battalions (MICC to SICC).

    ECCM OPERATIONS
    3-317. The Patriot system counters ECM in a variety of ways. The fire unit performs the main effort to neutralize ECM. Using the repertoire of waveforms within the radar, frequency diversity, or a combination of both, the Patriot system is effective in the ECM or chaffs environment. If jamming is so intense that the radar cannot determine target range, then the fire unit reports the information as a strobe (azimuth and elevation) to the ICC, which then performs triangulation and provides the needed range data to the fire unit.
    3-318. Triangulation requires track data from several fire units on the same target source, so overlapping coverage is an important element in Patriot defense design. The standoff jammer counter (SOJC) feature, using the virtual target (VT) process provides the Patriot system with an excellent capability against a range denied formation of SOJs. The strobe engagement mode (SEM) also provides the fire unit with the capability to engage range denied targets. The Patriot system has been extensively tested in severe ECM environments, to include the complete range of jamming, chaff, and their combinations, and has performed outstandingly.

    In a jamming environment the TVM technique is still usable because the system can measure range difference and as it already has the angular measurement of the target it can determine the difference in path length without loss of range resolution.
    It has the same range resolution as a non-jamming target engagement.
