摘要
提出用二分项采样法实现直接中频采样 ,而数字式检波器采用数字内插法。应用贝塞尔插值法 ,同步恢复数字接收机中两正交通道 I支路采样和 Q支路采样 ,满足现代雷达信号处理系统的要求。
It was suggested that direct intermediate frequency sampling was approached by two branch sampling, otherwise digital product detector was adopted to digital interpolation. Bessel interpolation can meet modern radar signal processing system's needs in accordance with regaining both I and Q components sampling of quadrature channels in digital receiver.
