According to the usage requirements and telecommunication index requirements of a certain radar detec-tion front end,the overall structure design realized the mutual transformation of radar mobile deployment and fixed deployment through integrated design.The performance of the radar was improved by increasing the array aperture,and hence detection capability of low altitude and ultra-low altitude aerial targets.In order to meet various trans-portation requirements,the antenna must be folded in traveling status.Considering the development requirements of a certain radar,the related technical research of"Error analysis and control technology of front-end folding array"was carried out,and the technical method of folded array error analysis and error control were proposed.The proto-type trial production and array unfolding/folding test of the folded array have been completed.The results showed that the folding error analysis and error control technology proposed in the scheme has certain engineering guiding significance.
