> Maritime professionals must understand how wavelength differences impact radar performance in challenging conditions

## Key points

- X-band radar (3 cm wavelength) offers higher resolution, making it better suited for short-range detail and target discrimination.
- S-band radar (10 cm wavelength) provides better performance in heavy rain and adverse weather due to reduced signal attenuation.
- Choosing between X-band and S-band depends on the specific maritime application, whether close-in fishing, harbor navigation, or offshore passage-making.

For the latest segment of “Fact or Fiction” by [Icom](https://marketscale.com/shows/icom/), Captain Kelly shines a spotlight on the technological showdown between X-band and S-band radars and particularly how they're relevant to maritime navigation and safety. This discussion comes at a time where it has become crucial amidst increasing reliance on radar technology for precision in adverse conditions.

She also takes a look into the functional differences and applications of three centimeter (X-band) and 10 centimeter (S-band) radars. She also shared from personal experiences, comparing their effectiveness based on range and resolution. On this episode, she offers a practical guide, weighing the pros and cons of each radar type to determine which might be best suited for specific maritime activities, from fishing to long-distance voyages.
