Abstract
The invention discloses a method for splicing a large-area reflector antenna comprising multi-panel units. The large-area reflector antenna comprising the multi-panel units is widely applied to the fields of radars, antennas and building roof systems. Such structure is characterized in that a plurality of small-area panel units are generally used and spliced into the large-area reflector antenna according to a certain of rules; a certain requirement is brought to the boundary dimension, the surface precision and the appearance quality. The method mainly comprises the steps of processing different geometric characteristics (such as angle end, straight side and arc side) of the external profile of the whole structure of the large-area reflector antenna by the corresponding positioning method; positioning characteristic panels in an outer ring; then splicing other panels in the outer ring; finally splicing the rest panels to the inside by layers; separating plates are pre-inserted between the panel units during splicing. With the adoption of the method, the size accuracy of the large-area reflector antenna and the uniformity of seams can be ensured, and thus the precision and the aesthetics are improved; meanwhile, the standard process enables convenient operation.
