| 摘 要： | 通过对静电目标特性的介绍,了解到静电探测器采集到信号是个低频的变化过程.为了准确的识别目标,提出一种基于数字综合算法的干扰抑制滤波器方法.该方法通过在滤波器频率响应的副瓣区放置大量的干扰信号,改变干扰信号的功率强度,从而自适应地控制滤波器频率响应的副瓣电平.这种方法所设计的滤波器,在其副瓣区域可以设计为任意形状,很容易满足实际应用的要求.设计实例证实了这种方法的有效性. |

| Abstract: | Introduces electrostatic target character,the signal collected from electrostatic sensor is a low frequency change process.For truly distinguishing target from noise,a new method for the design of the filters is given by utilizing the numerical synthesis algorithm for restraining noise.The frequency response of the filter designed by this method not only has wide and deep null at the zero region,but also has arbitrary sidelobe behavior.This method is effective through design examples. |
