The invention discloses a radio frequency array feed system fault positioning method and system, and belongs to the technical field of radio frequency simulation, and the method comprises the steps: responding to the detection that the dynamic range of an attenuator is smaller than a first preset threshold value, and positioning the fault as the attenuator; in response to detecting that the phase shifting range of the phase shifter does not meet a second preset threshold value, positioning the fault as the phase shifter; obtaining a theoretical value and an actual value of the amplitude of a system output signal, calculating a difference value between the theoretical value and the actual value, finding out an abnormal antenna of which the difference value is greater than a third preset threshold value, obtaining a control word of the abnormal antenna, and judging a mapping position of the abnormal antenna on the switch matrix according to the control word, according to the mapping position, judging the positi
