摘要：
This paper describes a technique for digital down-conversion from the final intermediate frequency within a radar receiver. The intermediate frequency signal is digitized directly and the baseband in-phase and quadrature channels are generated digitally to give excellent amplitude match and phase orthogonality. The algorithm is described in detail and the performance of a prototype down-converter is shown with an intermediate frequency 60 MHz.
