Abstract： Channel amplitude and phase eror correction ensures the high-precision beamforming and signal processing of PhasedArrayRadar （PAR）systems，significantlyimprovingradar performance.Channelamplitudeandphaseerorcorrection is achieved through equalizers.Thecore issueof errorcoectionishow todesign theequalizer effcientlyandaccurately.To addressthe problemof determining theorderof the equalizer，this paper proposes asimple frequency-domainequalizererror evaluationmethodByestimatingtheerrorbetweena givenequalizerandtheideal equalizer，the methodquicklyapproximates thecorrectionerrorsforequalizersofdiferentorders，allowingfortheevaluationoftheirperformance.Basedontherequired corrctin eror，the appropriate equalizer ordercanbe selected.Furthermore，this paper presents anequalizer design method basedon frequency-domain error minimizationcriteria，which isusedtodesigntheresponseofanequalizer withagivenlength. Simulation experiments show thatthe proposed equalizer design methodcan eficiently determinethe equalizer order and outperforms traditional frequency-domain design methods.
