天线罩误差对无线电制导导弹性能的影响

The Effect of Radome Aberration on RF Guided Missile

通过对天线罩误差形成原因的分析,提出了一种更合理的天线罩误差模型;基于该模型,研究了天线罩误差对制导系统稳定性的影响,分析了不同噪声源下各参数对无量纲化脱靶量的影响,为优化天线罩设计和气动外形设计提供依据,以确保天线罩和气动设计之间取得合适的平衡,使系统能够在实际可能出现的参数范围内工作良好。

Based on the reason of radome aberration, a reasonable radome aberration model was established, the effect of radome aberration on stability of RF guidance system was studied, the effect of parameters on nondimensional missdisrance was analyzed under different noise source. The simulation results provide a basis for optimal design of radome and aerodynamic configuration, to ensure the balance between radome design and aerodynamic configuration design, to make sure that RF guidance system works regularly in the range of possible parameters.
