Abstract: Low-cost,low-ower,and miniaturized broadbandelectronic reconnaissance equipment can give fullplaytothe advantages of individual soldier-portableand close-range reconnaissanceoperations.Angle measurement acuracy is oneof the keytechnicalindicatorsforreconnaissncesystems.Thispaperconductsananalysiscenteredontheclassicdsignofacircular reconnaissancearry.Firstly,te principleof theangle measurementalgorithmbasedonMUSICspectrumestimatioisntroduced. Secondly,theinfluencing factorssuchas Signal-to-NoiseRatio(SNR),amplitudeand phaseconsistencyofreceivechaels andDirectionofrival (DOA)of sigalsareanalyzed,andtheangle measurementaccuracyuderdiferentinfuencingfactors is simulatedandcalculated.Finallbasedonthesimulationresults,teimpactlevelsofdiferent influencingfactorsonangle measurementaccuracyare given.Theconclusionobtainedcanprovide reference forthedesignofcircularreconaissncesystems.
