Which of the following is considered the normal operational range from a SART unit to a surface vessel?

Question 1 of 27070

Which of the following is considered the normal operational range from a SART unit to a surface vessel?

🔍 Key Concepts

• SART (Search and Rescue Transponder) is detected by a ship’s X-band radar (9 GHz), not by satellite • The effective range depends mainly on radio line-of-sight between the SART and the ship’s radar antenna height • Compare the options with the typical detection range of X-band radar for a small target like a SART

💭 Think About

• Is a SART designed for short-range homing by nearby rescue units, or for long-range detection like satellites and HF radio? • Looking at the choices, which distances seem realistic for a small radar target close to the sea surface, considering radar horizon limits? • Would a ‘normal operational range’ be closer to tens of miles, hundreds of miles, or only a few miles for a device meant to guide a ship in to your position?

✅ Before You Answer

• Confirm that a SART works with shipborne X-band radar, not with satellite systems • Think about radar horizon: low height above sea level means limited range • Eliminate any option that suggests a range more like satellite or long-range radio than short-range radar homing
