The 3-cm radar compared to a 10-cm radar with similar specifications will display what advantage?

• A. Better range performance in rain, hail, etc.
• B. Small targets in a mass of dense sea clutter at a greater range.
• C. Less sea return in choppy rough seas.
• D. A more maplike presentation for inshore navigation.

Answer: (D)

The advantage of a 3-cm radar compared to a 10-cm radar with similar specifications is a more maplike presentation for inshore navigation. The shorter wavelength of the 3-cm radar allows for better resolution, which is essential in inshore areas where navigation requires distinguishing between various features such as buoys, shoreline details, and potential obstacles. This enhanced resolution means that smaller features can be represented more clearly, providing the navigator with a more detailed and useful picture of the surroundings, crucial for safe navigation in confined or intricate waters. Thus, a 3-cm radar typically offers superior detail and representation, making it more effective for inshore navigation compared to the longer wavelength of the 10-cm radar.
