摘要
Abstract
Amplitude-comparison direction finding is a widely used direction-finding technology in electronic warfare.However,due to its inherent direction-finding principles,the amplitude-comparison direction-finding systems inevitably exhibit random and systematic errors.To improve the accuracy of direction-finding systems,this paper analyzed the principles of mono-pulse amplitude-comparison direction-finding systems.Through theoretical study,the influencing variables at the system output end were identified.A comparison was made between the angle-of-arrival resolution in dual-channel and quad-channel amplitude-comparison direction-finding systems.After that,systematic errors under four conditions were investigated,including channel imbalance,beam configuration,beam width,and voltage amplification.The validity of these analyses was verified through simulations,providing theoretical references for the design and improvement of related equipment.关键词
