| 摘 要： | 提出一种基于离散傅立叶变换的战术导弹天线罩瞄准线误差的建模方法。利用半实物仿真系统把天线罩瞄准线误差引起的战术导弹导引头的输出指令采集下来,反推天线罩瞄准线误差模型,并利用得到的天线罩瞄准线误差模型进行天线罩瞄准线误差补偿系统试验,试验表明该补偿系统达到很高的补偿精度。

| Abstract: | An approach for modeling the missile radome error based on discrete Fourier transform is presented in this paper. The output of a seeker mounted in the missile caused by the radome error is gathered by the semi physical simulation system, and the model of the radome error is calculated. The test for compensating for the radome error has been done, which is based on the highly precise modeling. |
