The outer most complete circle, (if the ship has it in its equipment inventory) is the Radar range.
The next larger complete circle is the ships Visual range. These two complete circles can be confusing. If there is only one, its the Visual range. If there are two, the Radar is farther out than the Visual.
The next partial circle, that does not cover the stern of the ship, is the Hydrophone (Passive Sonar) range.
The smallest, usually half circle, that extends beyond the bow of the ship is the Sonar (Active Sonar) range.
=========
Planes will have the first two circles also.
Radar, if so equipped.
Visual, in either a complete circle, or similar to the Hydrophone shape due to the cockpit interference of the over shoulder view.
