Abstract :
A new multigate Doppler system using second-order sampling is proposed. To reduce the hardware complexity and to eliminate the balancing problem between in-phase and quadrature signal channels in conventional systems, the proposed system uses a single signal processing channel. This system can be used in a multigate Doppler system and implemented in a full digital fashion
