摘要
The influence of distortion of a shaped beam reflector on the radiation characteristics of an antenna under shock wave is studied. The far field of a shaped reflector antenna is modeled and analyzed based on the physical optics (PO) method. Results of measurement and calculation are compared when the shaped reflector is not distorted, and good agreement is obtained. The radiation characteristics of the antenna are studied when the shaped beam reflector are distorted by shock waves, including the value the location and the area of distortion. The results show that the distortion affects chiefly on the horizontal radiation patterns, and less on the vertical ones.
