The Design of Digital Multi-spots Balanced Weak Signal Instrumentation

在数字信号检测技术中,针对从强噪声信号中提取微弱信号的难题,本文深入分析了几种常见的微弱信号检测方法,从实现难度、检测的实时性等方面进行了对比,提出了基于数字式多点均衡策略的微弱信号检测方法。给出了该微弱信号检测仪的具体实现方案和技术手段,并从理论上分析了该检测仪的性能,验证了多点均衡策略的可行性。

As the digital signal examination technology, in view of the difficult problem that withdrew the weak signal from the strong noise signal , this paper has thoroughly analyzed several common weak signals examinations method, from realization difficulty, examination timeliness aspect and so on, has proposed weak signal examination method based on the digital multi- spots balanced strategy. Has produced this weak signal instrumentation concrete realization plan and the technical method. Besides that, and theoretically has analyzed this instrumentation performance, which confirmed the multi- spots balanced strategy feasibility.
