机械误差对仿真中抛物面反射器特性的影响

Analyse Mechanical Errors to Affect Characteristics of Paraboloid Reflector in the Simulation

在射频目标仿真中,影响导引头跟踪误差的主要有目标模拟器的机械运动和抛物面反射器的机械误差(包括表面误差和馈源支架的安装与变形误差)。其中抛物面反射器的机械误差主要影响相位。本文分析了各种误差之间的关系,并根据工程设计需要建立了机械误差与相位关系的数学模型。

Seeker's track errors are mostly affected by mechanical movement of target simulator and mechanical errors of paraboloid reflector include surface errors and fixing and distortion errors of feedbeek source's bracket which mostly af- fect phasic in the simulation of radio target.The paper analyses connections of errors and sets up a math model of me- chanical errors with phasic in order to engineering designs.
