【摘要】 在分析传统超宽带雷达接收机在多通道数据采集中存在问题的基础上 ,提出了新的超宽带信号的双通道数据采集系统的设计方法。在这种方法中 ,采用小波理论设计频域接收机中关键的频带分割滤波器 ,采用多分辨理论的方法进行数据恢复 ,并导出了对实际模拟滤波器频率特性进行补偿的方法。更多还原

【Abstract】 By analyzing the problems in the design of ultra-wide band radar receiver, a new method is proposed in this paper. In the method, a new kind of channel dropping filter is designed by using multiscale method of wavelet theory. And the compensation method in the practical design is also discussed.更多还原
