最大熵谱估计在反坦克导弹系统仿真模型验证中的应用

Applying Maximum Entropy Spectral Estimation to Verify Simulation Models for Antitank Missile Systems

针对反坦克导弹系统动态过程仿真的输出具有短时序、低信噪比的特点,研究了应用最大熵谱估计验证导弹系统仿真模型有效性的方法,并结合某型号反坦克导弹制导系统的仿真数据和理论计算数据给出了最大熵谱估计的应用结果。用最大熵谱估计对仿真模型进行验证可有效地解决导弹系统仿真模型验证过程中的两大难点,即比较判断时要求序列具有独立性问题及短时序、低信噪比信号的高分辨力提取问题。

Aimed at the singularity that dynamic process simulation output for antitank missile systems is of the short sequences and low signal-to-noise ratio,the method of applying maximum entropy spectral estimation to verify the validity of simulation models for missile systems is presented in this paper. With the simulative data and theoretical calculation data of antitank missile guidance systems of a type, it is given in this paper that the verifying outcome is attained by the method of maximum entropy spectral estimation. Applying maximum entropy spectral estimation to verify simulation models can effectively solve two problems in the process of verifying simulation models for missile system. One is the independence of the time serials, and the other is the high resolution of the short sequences and low signal-to-noise ratio signals.
