Abstract: The present invention relates to a reflector antenna for tracking a mono-pulse for a manned/unmanned moving object which rapidly moves from a distance, and, more particularly, to a feeding position control device of a reflector antenna which is capable of changing a beam width and a tracking range of a mono-pulse. The apparatus of the present invention includes a reflector antenna for generating a sum signal by synthesizing a multi-beam pattern formed through four feeding antennae in a feeding unit; a mono-pulse reception unit for detecting the level of the generated sum signal; and a feeding position control unit for sequentially changing a position of the feeding unit according to the level variation of the sum signal relative to a reference level of the sum signal with the maximum separation distance. The feeding unit position control unit increases a beam width and a tracking level of the mono-pulse by changing the position of each feeding antenna if the level of the detected sum signal is greater than the reference level of the sum signal in case of the maximum separation distance.
