Compact Range System with Double-cylindrical Reflectors
Product Details
Product features
a. Longer equivalent focal length
b. Lower cross polarization
c. The anechoic chamber has small impact on the reflective activity level
Product Description
The CATR with double cylindrical reflectors uses parabolic cylindrical with two curved surfaces in perpendicular each other to calibrate the spherical waves sending by the feed. The secondary surface calibrates the one-dimensional wavefront to cylindrical waves firstly, the main surface calibrates another one-dimensional wavefront to plane wave quiet zone. The single curved reflector is easy to be manufactured and use vacuum forming technology with lower cost. The equivalent focal diameter ratio of main surface is bigger than single reflector which reduce the unevenness of spatial attenuation and improve cross polarization.
But it can’t eliminate cross polarization components of reflector caused by geometric structures. The advantage is easy to be manufactured and be lower cost.
