Marine navigation radar is a traditional radio navigation equipment, which plays an important role in locating ships offshore, guiding ships into and out of ports, navigating narrow channels and avoiding reef collisions. It is widely used in all kinds of marine operations of civil ships, and is known as "the indicator lamp in the harsh navigation environment".

We measured the human-computer interaction factors under marine conditions in this marine equipment. Both the front-end radar and the information processing unit box use the protruding stripe strike force to realize real-time heat dissipation; the position of the screw hole is cleverly set, and the disassembly and maintenance become simple and fast. Relying on the innovative tripod structure, the equipment can calmly face the challenges of various harsh navigation environments.
