对红外制导系统的噪声分析与动态模拟

Noise Analysis and Dynamic Analogies in Infrared Guidance System

本文基于近红外制导系统噪声分析的框架模型,在分析探讨主要噪声源的基础上,给出了基本噪声立意,建立了探测器等组成部件基本噪声的功率谱分析式,设计出一种以红外探测嚣为抑制主体的减噪系统。通过目标、误差响应率的测定与跟踪试验获得较好的效果。

Based on the frame model of noise anaysis for near infrared guidance system, this paper gives the conception of basis noise, sets up an analytical formula of power spectrum for the basic noise in detector assemblies on the basis of exploring primary noise sources, makes a design for the noise reduction system with the infrared detefor as its main body and achieves good results through the determination of target, error responsivity and tracking test.
