为了解决传统气象雷达差频信号中含有较为复杂的噪声信号,导致气象雷达测距精度较低的问题,对基于椭圆滤波器的气象雷达差频信号滤波电路进行可靠性研究。根据气象雷达差频信号频带和噪声频率的特点,分别设计椭圆低通函数、高通滤波器,利用级联的方式组建带通滤波器,实现基于椭圆滤波器的气象雷达差频信号滤波电路可靠性研究。相关实验研究结果表明,基于椭圆滤波器的气象雷达差频信号滤波电路能够有效降低噪声干扰,同时提升气象雷达差频信号的质量,具有较高的可靠性。

In order to solve the problem that the difference frequency signal of the traditional weather radar contains complex noise signal,which leads to the low ranging accuracy of the weather radar,the reliability of the difference frequency signal filter circuit of the weather radar based on the elliptical filter is ording to the characteristics of frequency band and noise frequency of difference frequency signal of weather radar,elliptic low-pass function and high-pass filter are designed respectively,and band-pass filter is constructed by cascading to realize the reliability research of difference frequency signal filter circuit of weather radar based on elliptic experimental results show that the filter circuit based on elliptical filter can effectively reduce noise interference and improve the quality of difference frequency signal of weather radar,which has high reliability.
