What is the most common type of RADAR antenna used aboard commercial maritime vessels?
⢠Modern marine RADAR scanner designs on commercial ships ⢠Differences between dish (parabolic) antennas and bar-type (open array) antennas ⢠Why slotted waveguide arrays became common on ship bridges
⢠Picture the RADAR unit you most often see on photos of ship bridgesâdoes it usually look like a dish or like a long horizontal bar? ⢠Which of these antenna types is best suited for creating a narrow horizontal beam while staying low-profile and rugged in a saltwater environment? ⢠Which option matches the "open array" scanners commonly mounted on masts and wheelhouse tops of commercial vessels?
⢠Identify which answer choice corresponds to the long, bar-shaped scanner commonly seen on merchant ships ⢠Eliminate antenna types that are more typical of satellite dishes or shore-based communications towers than ship RADAR ⢠Confirm which type is specifically known as a bar or open-array marine RADAR antenna in training materials and equipment catalogs
