Adaptive multiple-beam antenna for simultaneous reception of multiple sources

摘要

Abstract: We consider the problem of adaptive reception of multiple sources by using a set of multiple simultaneous beams. This can be achieved by high-resolution direction finding followed by optimal beamforming for each source. In the first stage, the source estimation processor determines the number of sources and their angular locations. In the second stage, the information derived in the first stage is used to form multiple simultaneous beams. Each beam is designed such that it has optimal reception of one source while nulling out all the other sources.!13
