N2 - A low-cost reflector used in large-scale compact antenna test range (CATR) with Φ6.0m quiet zone and 0.5∼110GHz operating frequency is developed. Firstly, the geometry dimension, dividing scheme and structure form of the reflector are designed according to electrical requirements. Then, vacuum forming based on reconfigurable discrete nail mould (RDNM) is developed to rapidly and low-costly manufacture high-accuracy reflector with honeycomb sandwich structure. Due to extra-large area, the whole reflector is divided into many small panels to be fabricated separately. Meanwhile, steel framework and adjustment mechanism are designed to install and adjust all these panels. Then, a closed-loop adjustment system is constructed by adjustment mechanism and commercial laser tracker to adjust and align all these panels on site. Through final alignment, the root mean square (RMS) of surface error of the whole reflector comes up to 28μm.
