The invention relates to the technical field of radar installation, in particular to an airborne meter-wave radar transmitting antenna midair folding and unfolding mechanism which can fold and unfold a meter-wave radar transmitting antenna in the flying process of an aircraft. The folding and unfolding mechanism is mounted on an aircraft wing, a triangular support is hinged onto the wing through a first vertex, a first actuating cylinder and the support are positioned in the same plane, one end of the first actuating cylinder is hinged to the wing, the other end of the first actuating cylinder is hinged to a third vertex of the support, a connecting rod and the support are positioned in the same plane, one end of the connecting rod is hinged to a second vertex of the support, the other end of the connecting rod is fixedly connected with the transmitting antenna, a second actuating cylinder and the support are positioned in the same plane, one end of the second actuating cylinder is hinged onto a beam between the first vertex and the second vertex, and the other end of the second actuating cylinder is hinged to the connecting rod. The airborne meter-wave radar transmitting antenna midair folding and unfolding mechanism can drive the support and the transmitting antenna to rotate through the first actuating cylinder, so that the meter-wave radar transmitting antenna in the flying process of the aircraft is folded and unfolded.
