This application solve this marine radar plotting problems: - Determine kinematic data of a target like CPA (Closest point of approach) and TCPA (Time of CPA) - Determine evasive maneuver by turn to starboard, left and speed reduction with single target. - Determine the current. - Determine maneuver to escape. - Determine rescue maneuver. - Determine evasive maneuver by turning to the right and to left with two targets. - Calculate the detections by analyzing own ship and target positions In addition to the analytical resolution is a graphics representation on the radar sheet, with scale speed and adjustable distance in manual or automatic mode. Also in the graph it is selectable the representation of the true motion or relative motion.
