| Abstract: | Based on the digital signal processing theory, this paper discusses the principle the design of Digital Quadrature Modulation (DQM) and data interpolation and digital filter. Based on these works, the design of hardware of Digital Quadrature Modulator is given. In signal reconstruction of Radar clutter, the proposed approach archived higher signal reconstruction accuracy than that of Liner Quadrature Modulation (LQM). |
