摘要
研究用于空间目标探测的红外光谱仪信号处理技术。采用光路差分调制的方法实时扣除背景红外辐射,并采用锁定放大器进行微弱信号的检测。采用二级跟踪方法对目标像斑进行精密跟踪与定位。实验结果良好,电路噪声水平与动态范围满足要求,系统可行。
The signal processing techniques of infrared spectrum radiometer for detecting spatial objects was investigated. It introduces the method of modulated light subtracting infrared radiation of atmosphere and background as well as the method of phase-lock-loop detecting feebleness signal. It also takes two steps to confirm the position of target＇s image. The result of experiment is excellent, the signal-noise rate is high and the system is effective.
