Aiming at the complicated electromagnetic environment around airdrome,the in-phase and out-phase synthetical field pattern produced by the secondary radiation of similar-antenna radiator is analyzed with electromagnetic wave theory and the classical signal transfer arithmetic. The Influence of in-phase and out-phase synthetical electric field on aeronautical radio di-rection-finding accuracy is researched emphatically. The model was established. The simulation validation of result was conduc-ted. The research has a certain reference value for the surrounding buildings,direction-finding error analysis,tactical perfor-mance forecast of aeronautical radio direction-finding equipment.
