摘要
Abstract
Low-cost,low-power,and miniaturized broadband electronic reconnaissance equipment can give full play to the advantages of individual soldier-portable and close-range reconnaissance operations.Angle measurement accuracy is one of the key technical indicators for reconnaissance systems.This paper conducts an analysis centered on the classic design of a circular reconnaissance array.Firstly,the principle of the angle measurement algorithm based on MUSIC spectrum estimation is introduced.Secondly,the influencing factors such as Signal-to-Noise Ratio(SNR),amplitude and phase consistency of receive channels and Direction of Arrival(DOA)of signals are analyzed,and the angle measurement accuracy under different influencing factors is simulated and calculated.Finally,based on the simulation results,the impact levels of different influencing factors on angle measurement accuracy are given.The conclusion obtained can provide reference for the design of circular reconnaissance systems.关键词
