The Goalkeeper has two radar sub-systems, one to find threats and another to track and engage them, which operate together to identify and prioritise targets and engage the highest priority one.

The 2D [[I band (NATO)|I band]] search radar, which can handle up to 18 targets at once, generates a threat picture which the gun system uses to identify and prioritize threats.  The system has [[identify friend or foe]] (IFF) functionality to rule out friendly traces.<ref name="rnn">[http://kitsune.addr.com/LCF/goalkeeper.html Goalkeeper CIWS] {{webarchive|url=https://web.archive.org/web/20060218091832/http://www.kitsune.addr.com/LCF/goalkeeper.html |date=2006-02-18}} at the Royal Netherlands Navy LCF Frigate information page</ref> The tracking radar operates in both [[I band (NATO)|I band]] and [[K band (NATO)|K band]] to enable quick acquisition on the threat bearing. Data from both the I band and K band return signals indicate target range and can be used to identify, and respond to the use of, [[electronic countermeasures]] (ECM). The dual-band system also reduces the effect of [[Clutter (radar)|clutter]], which can mask the target at low altitude. A camera system on the assembly provides a visual fall-back for the system operator.
