The outer red circle on the radar screen is the border of the AIS guard zone and the smaller blue rings are the outer and inner circle of the radar guard zone. The two echoes seen on the screen are both fishing boats who will alert an alarm when entering the radar guard zone(none of them had AIS).

Echoes from Ibiza seen in the lower left part of screen
