Vibrating Noise Restraint of Multi-Sensor IR Seeker

对一种多元探测红外位标器的振动噪声进行了研究。列举了可能产生红外噪声的类型,分析了振动噪声产生的原因,建立了振动噪声的传递函数,并提出用减振的方法即隔离弹体振动的方法降低位标器的振动噪声。根据此位标器的具体特点,建立了减振系统的数学模型,得到位标器振动模型的微分方程并对该微分方程求解。在实际应用时用此种方法成功地降低了位标器的振动噪声。

This paper gives a research of vibrating noise of a muhi-sensor IR seeker. In this article, several kinds of Infra-noise which is possibly created are presented,the reason which brings vibrating noise is analysed,and the transfer function of the vibrating noise is constructed. A method is presented which can be used to reduce the vibrating noise by decreasing the vibrating amplitude or separating the vibration of missile from the seeker. In according to the characteristics of the seeker, a kind of mathematical model of decreasing the vibrating amplitude is set up. The differential coefficient equation of vibrating model of seeker is derived. In practice, the application of this method reduced the vibrating noise of the seeker successfully.
