Editing Phalanx CIWS (section)

===Radar subsystems===
The CIWS has two antennas that work together to engage targets. The first antenna, for searching, is located inside the radome on the weapon control group (top of the white-painted portion). The search subsystem provides bearing, range, velocity, heading, and altitude information of potential targets to the CIWS computer. This information is analyzed to determine whether the detected object should be engaged by the CIWS system. Once the computer identifies a valid target (see details below), the mount moves to face the target and then hands the target over to the tracking antenna at around {{convert|4.5|nmi|km|0}}. The track antenna is extremely precise, but views a much smaller area. The tracking subsystem observes the target until the computer determines that the probability of a successful hit is maximized and then, depending on the operator conditions, the system either fires automatically at around {{convert|1|nmi|km|0}} or recommends fire to the operator. While firing 75 rounds per second, the system tracks outgoing rounds and 'walks' them onto the target.<ref>{{cite web |title=Last ditch defence – the Phalanx close-in weapon system in focus {{!}} Navy Lookout |url=https://www.navylookout.com/last-ditch-defence-the-phalanx-close-in-weapon-system-in-focus/ |website=www.navylookout.com |archive-url= https://web.archive.org/web/20210619100156/https://www.navylookout.com/last-ditch-defence-the-phalanx-close-in-weapon-system-in-focus/ |archive-date=June 19, 2021 |date=August 10, 2020 |url-status=live}}</ref>
