Provided are a cooperative polarization skylight background radiation measurement device and method, belonging to the field of polarized radiation remote sensing. The device includes a measurement probe, a lower computer control system, a two-dimensional turntable, a base and data transmission interface, as well as an upper computer. The method includes the following steps: the cooperative skylight background radiation polarization measurement device is initialized, a polarization wheel is returned to a zero position, and dark noise is collected by a double-path spectrometer; then a measurement mode is selected for measurement; and finally, spectral polarization data of each wave band acquired by the double-path spectrometer and a division-of-focal plane polarization camera is transmitted to the upper computer through a data line, original spectral light intensity data is calculated according to a measurement principle, and finally a degree of polarization and an azimuth angle of polarization are obtained.
