Ir remote wavelength
WebFrom a satellite in space operating at a wavelength of about 5 cm (C-band radar), in order to get a spatial resolution of 10 m, you would need a radar antenna about 4,250 m long. (That's over 47 football fields!) An antenna of that size is not practical for a satellite sensor in space. WebInfrared light (IR): Electromagnetic radiation with a wavelength between 700 mm and 300 um, which equates to a frequency range between approximately 1 and 430 THz. IR radiation is just below visible light on the …
