The traditional radar moving target receiver consists of analog phase-locked circuits. Due to the unstable operation of analog circuits, the performance of the whole system is greatly limited, such as improvement of system improvement factor and improvement of SCV performance. A new scheme of all-digital radar moving target receiving system is designed, which can effectively eliminate or reduce the impact of various factors on the system performance when compared with other high-performance radar digital signal processing systems. The system has the advantages of simple structure and cost Low obvious advantages. Several important issues in the concrete implementation are also discussed and the experimental results are given
