摘要
Abstract
Aiming at the problem that the interferometer system with a small number of array elements cannot make full use of the DBF array antenna elements when extracting array elements from the DBF array antenna to form an interferometer direction finding system,an interferometer direction finding signal processing method based on the DBF array antenna is proposed.By improving the interferometer direction finding algorithm,all the array element channel data extracted from the DBF array antenna are involved in the direction finding operation to improve the ambiguity resolution probability.At the same time,the method of averaging the correct direction finding results of multiple equal-length baselines is used to further improve the direction finding accuracy and improve the direction finding performance of the system.The effectiveness of the method is verified by theoretical derivation and simulation experiments.关键词
