A Method for Seeking Low-Redundancy Large Linear Arrays in Aperture Synthesis Microwave Radiometers
TL;DR: The general structure of large LRLAs is summarized, and a novel stochastic optimization technique, ant colony optimization (ACO), is applied to the search for low redundancy arrays, and an efficient method is proposed for a rapid exploration for optimal array configurations.
