Accepted Answer

200-1000m Systems like Radius and RadaScan operate using Frequency Modulated Continuous Wave (FMCW) radar technology in the microwave band. These are short-range, high-precision relative positioning systems typically used for station-keeping operations near offshore installations. Here is why this is the correct range: * **Technology Constraint:** FMCW radar for this application relies on transponders (responders) mounted on the target. The signal strength and the need for high precision limit the effective range compared to long-range navigation radars. * **Operational Reality:** * **Radius:** Typically has an operating range up to **550 - 1000 meters** depending on the specific model and transponder type. * **RadaScan:** Typically operates effectively up to **600 - 1000 meters**. * **Comparison:** * **10-50m:** This is too short; this range is more typical for laser systems (like early Fanbeam use) or very close quarters, but radar systems work well beyond this. * **5000m / 10000m:** These ranges are too far for these specific precision reference systems. Standard navigation radars or GNSS are used for these distances. Therefore, the **200-1000m** range is the only option that covers the standard maximum working distance for these systems.
