ABSTRACT

A laser has the characteristics of good monochromaticity, good directivity, good coherence, and high-brightness. Because of these, laser guidance technology plays a more and more important role in modern war. Besides, with the improvement of science and technology, laser simulators can simulate the targeting effects of the real firing weapons as exactly as possible. They have not only achieved their purpose in training, but have also cut down the expenses. In order to achieve the actual effect and imitate the fighting process in practical training, we need to develop a realistic simulator. This paper designs an emission device of an anti-tank missile laser simulator. It consists of a fiber-coupled laser diode with 915 nm wavelength, a collimating optical system which can compress the divergence angle from 218 mrad to 6.5 mrad, a zoom collimating and beam expanding system, and a rotary dual-wedge system. The advantages of this system are that it is simple, and can be easily installed and adjusted. It can simulate the return signals of the pulse laser simulator when it finds the range for the targets with different characteristics at different distances under various atmospheric conditions.
