Key Takeaways. Radar works on the principle of electromagnetic waves. S-band radar utilizes the microwave band in the electromagnetic spectrum, which ranges from 2GHz to 4GHz. The most notable advantage of S-band radar is it is less susceptible to atmospheric attenuation .

A single S-band boom antenna on each satellite (deployed after launch by a pyrotechnic device) enables the satellite to communicate with Earth . There are small backup antennas on the top of each satellite to provide backup communication as required.
