Main factors which affect secondy suveillance radar(SSR)measurement accuracy and calculates values of measurement errors are analyzed in this paper firstly.Generally it is difficult to apply some improving methods to decrease the errors because of the radar hardware system limitation.From point of view of radar data processing,we propose some valid methods to increase measurement accuracy such as the OBA self-correcting technique,the angle measuring method of least square and the error correction of range measurement,etc.Engineering application proves that the above-mentioned methods can improve SSR measurement accuracy effectively.
