At present, the scientific rationality of the allocation of structural accuracy indicators needs to be improved. It is necessary to sort out the corresponding relationship between structural accuracy indicators and telecommunication indicators, and analyze in detail the impact of each error influencing factor on structural accuracy, and provide a specific allocation plan in combination with typical radars to form antenna system pointing. The unified calculation method of precision makes the radar structure precision not only meet the requirements of use, but also reduce the implementation cost

[0004] At present, domestically, there is no exploration on the balance between radar structure accuracy design and telecommunication accuracy index, and the unified calculation method of antenna system pointing accuracy, and the typical high-precision radar structure accuracy design and implementation methods have not been systematically formed. Therefore, there is an urgent need to systematically develop radar structures.
