WebA nominal frequency range, from 8 to 4 GHz (3.75 to 7.5 cm wavelength) within the microwave (radar) portion of the electromagnetic spectrum. Imaging radars equipped with C-band are generally not hindered by atmospheric effects and are capable of imaging through tropical clouds and rain showers. WebTypically, these systems operate in the microwave (300 MHz–40 GHz) portion of the radio spectrum. Doppler radar detects the relative motion of an obstacle; i.e., detection requires either movement of the obstacle or the vehicle. Both types of radar are effective for detecting people, other vehicles, large rocks, and buildings.
