With each rotation the beam scans the surrounding surface. Any ships or obstructions reflect microwaves back to the antenna, displaying on the radar screen. Marine radars are X band or S band radars on ships, used to detect other ships and land hazards, to provide bearing and distance for collision avoidance and navigation at sea. [1]
A typical shipboard ARPA/radar system. A marine radar with automatic radar plotting aid (ARPA) capability can create tracks using radar contacts. [1] [2] The system can calculate the tracked object's course, speed and closest point of approach [3] (CPA), thereby knowing if there is a danger of collision with the other ship or landmass.
The frequency band of radar used on most ships is X band (9 GHz/3 cm), but S band (3 GHz/10 cm) radar is also installed on most oceangoing ships to provide better detection of ships in rough sea and heavy rain condition.
The Sea-Based X-band radar (SBX-1) is a floating, self-propelled, mobile active electronically scanned array early-warning radar station designed to operate in high winds and heavy seas. It was developed as part of the United States Department of Defense Missile Defense Agency's (MDA) Ballistic Missile Defense System.
A cruise ship tracker is exactly how it sounds; much like tracking flights or Amtrak trains, a cruise ship tracker allows you to see where any active ship is through either an app or a website ...
These are automated gun systems mounted on the deck of a ship that use radar to track the approaching missile, and then attempt to shoot it down during its final approach to the target. Anti-aircraft guns such as the Mk 45 5-inch (127 mm) naval gun or the AK-130; Electronic warfare equipment (such as AN/SLQ-32 Electronic Warfare Suite)
Diagram of the Aegis Combat System (Baseline 2-6). The Aegis Combat System (ACS) implements advanced command and control (command and decision, or C&D, in Aegis parlance). It is composed of the Aegis Weapon System (AWS), the fast-reaction component of the Aegis Anti-Aircraft Warfare (AAW) capability, along with the Phalanx Close In Weapon System (CIWS), and the Mark 41 Vertical Launch System
