The invention relates to a dual-wavelength polarized high-spectral-resolution laser radar device. Separation of a atmospheric molecular backscattering signal and an atmospheric aerosol backscattering signal is realized by using a confocal fabry-perot filter and a single-frequency polarized laser; and then the central transmitting frequency of the confocal fabry-perot filter and the emission laser frequency of the single-frequency polarized laser are locked in real time by using a frequency locking system, thereby realizing high-spectral-resolution detection. According to the laser radar device provided by the invention, the device is free from the wavelength restriction; and the spectral resolution capability and the frequency locking stability are high. The laser radar device can be applied to satellite borne, airborne, and ground-based platforms. |
