对于噪声测量系统来说,测量精度是其最重要的性能指标之一.在实际情况下,受系统各组成部分响应的影响,系统的宽带发射/接收信号往往会发生畸变,从而影响系统的测量精度.因此,对系统响应抵消方法进行研究十分重要.目前对系统响应抵消的应用较少,常用的方法主要是通过在频域上对系统响应进行抵消加权实现,具有运算量大、精度低,以及生成信号不连续等问题.为了克服以上问题,论文提出了一种基于FIR滤波器的时域系统响应抵消方法.经仿真验证,与频域系统响应抵消方法相比,该方法具有更高的运算效率和更高的精度,并可生成连续的系统响应抵消信号.
A System Response Cancellation Method Based on Time Domain
For noise measurement systems,the accuracy of measurement is one of its most important performance indicators.Influenced by the response of the system,the broadband transmit/receive signal is often distorted,which will affect the measure-ment accuracy of the system.Therefore,it is important to investigate the system response cancellation method.At present,there are few applications of system response cancellation,the commonly used method is realized by inverse weighting the system response in the frequency domain,with problems such as high computational complexity,low accuracy,and discontinuity of the generated sig-nal.To overcome the above problems,this paper proposes a novel method of time domain system response cancellation which is based on FIR filter.Simulations demonstrate that the proposed method has higher computing efficiency as well as higher accuracy than the previous method and can generate a continuous system response cancellation signal.
