Abstract:

The existing ship-to-air missile hit probability estimation methods are mainly studied from the perspective of single batch tests, but fail to consider the characteristics of multiple batches growth tests, which makes it difficult to accurately estimate the hit probability. In this paper, the two-dimensional normal projectile dispersion phenomenon of ship-to-air missile is taken as the entry point, the normal-inverse Gamma distribution is selected as the prior distribution of projectile dispersion parameters based on Bayesian method, and the prior information is merged to make up for the insufficient data in the small sample tests. The sequential constraint relationship is established between the projectile dispersion parameter values of each batch of tests, and the Markov chain-Monte Carlo (MCMC) method is combined with Gibbs sampling for Bayesian solution, so as to achieve the purpose of fusing multiple batches growth tests information. The research results show that this method can consider the characteristics of multiple batches growth tests compared with the existing single batch tests hit probability estimation method, and provide reference for ship-to-air missile hit probability estimation.

Key words: ship-to-air missile, hit probability, multiple batches growth tests, projectile dispersion, Bayesian, Markov chain-Monte Carlo (MCMC)
