Tolerance Analysis of Planar Phased Array Antenna

This paper analyzes the sidelobe deterioration of elliptical array antenna under the synthetical effect of element feed random amplitude - phase error,element random position error,element failure and row (or column) correlated random amplitude-phase error caused by row feed (or column feed). The analysis indicates that the residual sidelobe caused by the independent random error of element is essentially evenly distributed over the entire lobe region, the effect of correlated error is maximum in the plane orthogonal to the correlated directi on and is minimum in the plane parallel to the correlated diedction. This paper also analyzes the effect of antenna array deformation caused by the carrier vibration ,wind and gravity etc. on the pattern characteristics.
