How is a MOB search typically conducted using radar?

• A. Define search sectors, set appropriate range, use sweep patterns, and coordinate with rescue assets.
• B. Sweep patterns only with no sectoring.
• C. Ignore sectors and sweep randomly.
• D. Use a direct beam to the last known contact and ping.

Answer: (A)

A MOB search with radar works best when you approach it as a planned, area-wide effort rather than a single bearing or a random sweep. Start by defining search sectors around the last known position and the most likely drift paths, so you systematically inspect the probable area without leaving gaps. Then set an appropriate radar range that covers the entire sector and the most likely search area, taking into account sea state, weather, radar performance, and how long since the person disappeared. Use structured sweep patterns that move the radar beam through each sector in a predictable, repeatable way, which helps you build a complete picture of the area and increases the chances of detection as conditions or the target’s drift change. Coordinating with rescue assets is essential—assign sectors, share updates on any detections, and synchronize movements so coverage is efficient and resources aren’t duplicated. This approach maximizes detection probability and speeds up the overall rescue effort; sweeping randomly or fixating on the last known contact would miss areas where the person could have drifted, and ignoring sectors would leave significant gaps.
