In this paper,the synchronous design of multi-chip ADC high-speed acquisition system can be realized by using the test mode of analog-to-digital converter.The design can ensure the phase consistency between multiple channels in phased array radar,and ensure the accuracy of azimuth and pitch Angle measurement.The system was tested by external analog signal source,and the test results were analyzed by MATLAB to determine the phase rela-tionship between channels,and verified the functionality and stability of the design.
