A new small sample experiment and estimation method based on target maneuver sensitivity and maneuver distribution function is proposed. In this paper, we describe the fitted orthogonal function system and its uniform convergence sensitivity of the target maneuver to the hitting error sensitivity, and prove the uniform convergence of the approximation of the estimation expectation and the variance of the small sample method by using the measurement theory. The theoretical proof in this paper is that for this small sample experiment Method provides a theoretical basis.By comparing the large samples and small samples of the semi-physical simulation system, it is proved that the statistical results of this method are very close to the statistical results of large samples.This method is a new adaptive method that is adaptive to a variety of controlled variable- A New Method of Small Sample Experiment in Seeking Guided Weapon Hardware - in - the - Loop Simulation System
