Coverage Efficiency Optimization and Experimental Verification Based on Conjugate Matching Method

Reflector antennas are the primary configuration for large radio telescopes, and the optimization of beam synthesis technology in phased array feeds (PAFs), as their core components, directly determines system performance.Under ideal electromagnetic propagation conditions, each array element receives only the target signal component, allowing directional beam synthesis through simple phase compensation.However, in practical scenarios, the coupling effects of multipath reflections, artificial interference, and background noise result in spatially heterogeneous characteristics in the array-received signals.
