Aircraft attitude vibration of airborne early warning (AEW) radar can affect the detection performance and accuracy of targets. Considering that AEW radar based on a 3-plane array is affected by aircraft attitude vibration, A mathematical model for aircraft rolling and pitching has been established. Under the conditions of mono-pulse sum-difference, the influence of two types of vibrations on the accuracy of angle and height measurement was analyzed. The accuracy of height finding under various vibration angles is determined by conducting simulation experiments. The results of the simulations indicate a noticeable decrease in height finding accuracy due to the presence of vibration; when the vibration angle is greater than a certain angle, radar height information cannot be used due to the large mean square error; the rolling of an aircraft has a significant impact on the high accuracy of oblique photos, and the overhead view of an aircraft has a significant impact on the high accuracy of the forward array.
