The coherent signal processing is universal adopted in the modern radars.The key on signal processing is how to achieve high resolution base band digital quadrature I/Q demodulation.This paper details that the theory of radar direct IF sampling,and summarizes that serious kinds of typical methods of quadrature coherent detection.
