摘要
本文论述了应用高阶相关技术提高电视跟踪信噪比的方法。文中介绍了高阶相关技术的基本原理,并从理论上计算了在某些使用条件下,用高阶相关技术后得到的信噪比增益可达7分贝。最后做了定性实验,证明了用高阶相关技术提取弱视频信号是有效的。
In this Paper the method is discussed of the application of higher-order correlation technology to TV tracking for developing the gain of signal-to-noise ratio.
The basic theory of higher-order correlation technology is presented in the paper. By a theoretical computation in some conditions a gain up to 7 db can be obtained.
Finally, an experiment has been made to prove it effective to abstract a weak video signal by means of higher correlative technique.
