To address the issue that the tracking performance of shipboard mono-pulse digital receiver is affected by the tempera-ture phase stability,the reason for digital receiver phase variation is analyzed,and the relationship between coaxial cable temperature phase stability and tracking performance is analyzed theoretically.Based on engineering test and the characteristics of equipment,two phase calibration strategies for shipboard mono-pulse receiver are proposed.The feasibility is validated by experiment.The results provide a reference for the study of shipboard receiver dynamic phase alignment and tracking performance.
