Abstract：The ship attitude measurement errors affect the detection precision of shipboard radar on the target,further affect ship's operational effectiveness and viability. Based on the coordinate transformation,the mechanism of radar detection error is ana?lyzed to solve this problem. The error model that attitude measurement error affects the radar detection precision is established. The simulation experiment results indicate that radar ranging precision is related to the three attitude angle errors,the azimuth precision of radar measurement is mostly related to the yaw angle errors,the pitching angle precision of radar measurement is associated with pitch angle errors and roll angle errors. The radar detection precision is related to the size of attitude angle,and the detection errors are bigger when the attitude angles are bigger. The radar ranging error and the pitching angle measurement error are related to the az?imuth of the target.
