What is an S-band Radar?

S-band radars are specialized marine radar systems operating in the 2–4 GHz frequency band, ideal for long-range target detection and superior performance in heavy rain or fog. They are essential for navigation safety on SOLAS vessels, tankers, LNG carriers, and offshore platforms. At Ftron, we specialize in the supply, installation, service, and calibration of S-band radars from all major brands to ensure your vessel remains compliant and safe in challenging conditions.

Frequently Asked Questions (FAQs)

1. Why choose S-band radar over X-band?
S-band radars offer better performance in adverse weather conditions and are preferred for long-range detection on large vessels.

2. Is S-band radar mandatory?
For SOLAS vessels over 3000 GT, having both X-band and S-band radars is typically required.

3. Can you supply S-band radar spare parts?
Yes, we supply original and compatible spares including scanner motors, magnetrons, displays, and processors.

4. Do you support magnetron and solid-state radars?
Yes. We provide service for both traditional magnetron-based and modern solid-state S-band radars.

5. What tests are included in radar performance check?
Transmit power check, pulse width, tuning, gain, heading alignment, and bearing accuracy tests.

6. Can you integrate radar with ECDIS or AIS?
Absolutely. We provide radar overlays and interfacing with ECDIS, AIS, and VDR systems.

7. How long does radar installation take?
Depending on the vessel and access, typical installations take 2–4 days including sea trials and calibration.

8. Do you offer service in the Middle East and Asia?
Yes, our engineers cover UAE, Singapore, Egypt, Oman, Qatar, Bahrain, and India.

9. What’s included in an AMC?
Periodic inspections, calibration, software updates, component health checks, and emergency support visits.

10. Can you assist with radar retrofit projects?
Yes. We offer complete retrofit solutions, from dismantling legacy radar systems to installing and commissioning new ones.
