Propagation Characteristics
Good weather-target contrast. 3 cm wavelength detects rain and hail effectively. Range resolution improves with bandwidth. Attenuation in rain limits long-range use.
Regulatory Notes
Marine radar: 9.2–9.5 GHz (ITU). Meteorological radar: 9.3–9.5 GHz. Police radar: 10.5–10.55 GHz. All require licensing.
