动态目标图象的信号检测方法研究

Study on methods of detecting signals in dynamic object image

在信号处理中， 用普通相关方法对信噪比信号的检测经常得不到很好的结果， 本文给出了用双相关图象去除杂光背景干扰的算法。该算法与普通相关检测方法相比有１０ｄＢ左右的信噪比增益。

Poor detect ability with lower signal to noise ratio in signal processing often occurs when direct correlation method is used. To overcome this problem, new signal processing algorithms for dual correlated scene clutter removal to detect low SNR targets are derived. The algorithms can implement more than 10 dB in the detection of signal to noise compared to conventional methods.
