What does air-search radar determine in maritime operations?

Air-search radar in maritime operations is primarily utilized to detect and track aircraft, identifying their position, course, and speed. This capability is essential for maintaining situational awareness, particularly in defense scenarios where understanding the movement of potential threats is critical. By providing accurate information on the location and trajectory of aircraft, air-search radar systems assist in decision-making related to navigation, operational readiness, and defense strategies. Moreover, this information is vital for coordinating responses or actions in both defensive and offensive maritime operations.
