Abstract :
The in-field evaluation and validation of Semi-active laser guided weapons can be achieved by the laser target simulator. The composition and operation principle of the laser target simulator based on the transmissive structure are described in this paper, and the key instruction focus on the optical system parameters which the system required. The optical system is designed using to simulate the changes of the spot size, and the projection system is designed using to simulate the far-field target under the near-field conditions. The result shows that the spot simulated in optical system can achieve the ranges of 0.1mm ~ 18mm; the focal length of the projection system is 200mm, and the F number is 1.25, the MTF value is greater than 0.1 at the spatial frequency of 10 lp/mm under the condition of the exit pupil distance of 600mm, which satisfied the practical test requirements.
