Abstract

This paper is devoted to the relationship between the jamming effect of high-repetition-laser for semi-active laser guidance seeker and the capacity of seeker information processing and the style of the jamming signal. In this paper a set of semi-active laser guidance countermeasure of semi-physical simulation system was designed. The principle of the seeker was investigated from the signal level, and a variety of anti-jamming algorithm for signal processing was designed, and assessment scheme of jamming effect was provided. In the seeker search stage lays emphasis on the research of the influence of high-repetition-rate laser for seeker coding identification process. In the seeker tracking stage, the interference effect of different anti-interference measures was studied, such as the interference frequency, energy, position and interference time. The experimental results show that, the interference pulse energy is larger, interference source and target angle is larger and interference effect is more obvious. Improving the frequency of interference laser pulse will increase the probability of success of the interference, and reducing the width of the time window of seeker will enhance seeker anti-interference ability. A signal jamming effect evaluation scheme is provided to offer a full set of experimental platform and theory foundation for the through discussion of laser semi-active guidance interference.
