ABSTRACT
With the development of stealth technology, the threat of stealth aircraft with high speed and high maneuverability is increasing. Statistical distribution model can reveal dynamic RCS characteristics, which is an important part of anti-stealth technology. In this paper, the static RCS database is established initially. Combining with the level flight and the circling track models, two dynamic RCS sequences are obtained based on the static RCS database. Then, these dynamic RCS sequences are described by chi-square distribution model, log-normal distribution model and Weibull distribution model. The K-S test results reveal that the log-normal distribution has high accuracy. So, the log-normal distribution has good potential in anti-stealth.
