🔍 Key Concepts

• RADAR range calibration and what controls accurate range display (sweep/timing circuits) • Difference between bearing errors (like parallax) and range errors • Using independent reference objects or instruments to confirm a sensor’s accuracy

💭 Think About

• Ask yourself: which choice directly relates to how the RADAR paints distance (range) on the screen? • Which option deals with bearing only, and therefore would NOT fix a pure range disagreement? • Which options actually TEST or CORRECT the RADARs, and which just work around the problem without identifying the faulty unit?

✅ Before You Answer

• Verify which component of a RADAR system determines the correct timing of transmitted and received pulses for range display. • Check whether antenna parallax affects range, bearing, or both. • Confirm that using an average of two conflicting sensors does NOT identify which one is wrong, only gives a compromise.

On a vessel with two RADARs, one has a different range indication on a specific target than the other. How would you determine which RADAR is incorrect?

Check the sweep and timing circuits of both indicators for correct readings .

Triangulate target using the GPS and visual bearings.

Check antenna parallax.

Use the average of the two indications and adjust both for that amount.
