Design and Implementation of Radant Lens Test

Radant lens radar can form the linear phase gradient required for beam scanning, completing one-dimensional phase scanning. It is composed of many parallel metal plates, multiple layers of dielectric between the plates, and many parallel diodes in the same direction in each layer of dielectric To ensure the accuracy of the phase shift value, all diodes need to work properly. The number of lenses on a single array can reach several thousand, and the problem of how to conduct testing urgently needs to be solved. This article adopts a digital approach to design a lens testing board and software development” which can conveniently and quickly solve lens testing problems.
