Design on the optical system of laser semi-active seeking guided hardware-in-the-loop simulation seeker

The optical system performance of hardware-in-the-loop simulation seeker is the key to the effect of simulation experiment. The structure and characteristic of laser semi-active seeker and its optical system was analyzed. The optical system receiving threshold of sensitive energy,instantaneous field, seeking field, and so on were analyzed as well. According to the general principle of optical design and the special requirements of the laser semi-active seeking guided hardware-in-the-loop simulation seeker, an optical system with satisfying imaging quality was designed by using the ZEMAX software based on the technique parameters of some real missile. It is shown that the system can meet all kinds of parameters requirements with better imaging quality, which provides reference for related application.
