| Abstract: | This paper describes briefly the basic principle of angular tracking systems of coherent CO2 laser radar, discusses laser radar range equation, analyses quadrant detector tracking method and error character. Edge tracking is used for extended lambertian target. The frequency scanning and tracking narrow filter for advanced signal to noise ratio may be used to detect signal of the angular tracking system. The channels ununiformity effect and compensating method are discussed. |
