A high speed monopulse tracking radar antenna is provided to track a high speed flying object by reducing a weight thereof to rotate at high speed by using feed line pipes as a feed horn support. A parabolic reflector(10) is formed by filling honeycomb or expandable resin cells between a parabolic metal film and a parabolic insulator. A monopulse feed horn(20) is supported by feed line pipes(5), installed in a focus position(F) of the parabolic reflector, and supplies a total sum signal, a horizontal difference signal, and a vertical difference signal. A transceiver(30) is installed at a center of a back side of the parabolic reflector to receive the total sum signal, the horizontal difference signal, and the vertical difference signal. A housing(40) protects the transceiver. A driving unit tracks an object by rotating the parabolic reflector at high speed.
