新的寻的导弹半实物仿真系统小样本实验方法

针对自寻的制导导弹半实物仿真系统仿真实验造价昂贵的现实,对小样本实验进行了研究,提出了一种新的基于目标机动对命中误差灵敏度和机动分布函数的小样本实验和估算方法.文中描述了目标机动对命中误差灵敏度的拟合正交函数系及其一致收敛性,并用测度理论证明了小样本方法估算期望和方差的逼近的一致收敛性质.文中的理论证明为该小样本实验方法提供了理论依据.通过对半实物仿真系统的大样本和小样本对比实验,证明该方法的统计结果与大样本统计结果非常接近.该方法是一个适应于各种可控变参系统和自寻的制导武器半实物仿真系统小样本实验的崭新方法.

New Method of Small Sample Experiment for the Simulation System with Hardware in the Loop for Homing Missile

The small sample experiment method of a simulation system with hardware in the loop(HWIL) for radar homing missile is studied due to radar guider's high expenses, and a new method of small sample experiment is proposed based on the sensitivity of the target maneuver to the undershoot errors and maneuver time distribution function. The theory foundation of the method is given, which proves that the expectation and variance are uniformly convergent in measure space, and the orthogonal function series used to approach the sensitivity function is uniformly convergent. It is proved that the method is very effective compared with great sample experiment. The method can be applied to other small sample experiment of simulation systems with HWIL for homing missile and governable variable systems.
