Abstract With the rapid development of radar detection and calibration technology,the utility of high-resolution radar data in disaster monitoring and early warning,quantitative precipitation estimation,and other work has been significantly improved.Therefore,the requirements for the detection accuracy of weather radar and the accuracy of radar echo coordinates are becoming increasingly high.The article mainly focuses on the impact of radar echo consistency caused by the horizontal deviation of the antenna in the antenna feeding system,and proposes a error compensation method.Error analysis shows that this method is effective in high-resolution radar data comparison,and can further improve the accuracy of echo coordinate calculation and product mosaic application.
