Embodiment Construction
[0026] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0027] The present invention proposes a brand-new missile-borne omnidirectional telemetry antenna combination, whose task is to transmit radio frequency carrier signals to the ground station, and transmit information to the ground station when the missile is hit, so it is required that the missile always maintain Communication link with the ground measurement and control station. The attitude of the missile remains basically stable before atmospheric re-entry, and it begins to rotate after atmospheric re-entry. Since the telemetry system cannot obtain missile attitude information, in order to ensure that the communication link is not interrupted, an omnidirectional antenna design must be adopted. The telemetry equipment on the missile must work normally in all stages where the interception may occur, so the antenna and equipment cannot be instal...

The invention provides a supersonic-speed missile-borne combined omnibearing remote measurement antenna, and relates to the field of a missile-borne remote measurement antenna. The supersonic-speed missile-borne combined omnibearing remote measurement antenna comprises an elastic body and four quadrant antennas, wherein the four quadrant antennas are respectively a first quadrant antenna, a secondquadrant antenna, a third quadrant antenna and a fourth quadrant antenna, an outer wall of the elastic body is of a conical barrel-shaped structure, the four quadrant antennas are symmetrically and fixedly arranged on the outer wall of the elastic body, an included angle between two adjacent quadrant antennas is 90 degrees, the four quadrant antennas are perpendicular to the same plane of the elastic body, the first quadrant antenna, the second quadrant antenna, the third quadrant antenna and the fourth quadrant antenna are arranged in a clockwise way in a direction from a missile tail to a missile head, the four quadrant antennas are fixedly arranged in grooves of a surface of the elastic body, and an upper surface of an antenna cover is in smooth transition with the elastic body. By thesupersonic-speed missile-borne combined omnibearing remote measurement antenna, the interference caused by multiple antennas working on a large-size carrier with same frequency is prevented, signal lost caused by an overlap region is prevented, and the structural requirements of surface conformality of the elastic body and the antenna profile, and the like are reduced.
Description
technical field [0001] The invention relates to the field of missile-borne telemetry antennas, in particular to a supersonic missile-borne combined omnidirectional telemetry antenna. Background technique [0002] In modern high-tech local wars, such as the Gulf War, Kosovo War, Afghanistan War, and the recent Iraq War and Libya War, medium and long-range missile attacks have become one of the main effective means of attack. The missile is a controllable unmanned aerial vehicle with a warhead inside. The main difference between it and other conventional weapons is that technicians can guide the missile to fly according to the predetermined trajectory according to the needs, and can hit the target more accurately through the guidance system . [0003] When the missile is flying on a predetermined trajectory, ground technicians obtain data information such as its flight status through the missile-borne telemetry antenna. The data link is very important on the future battlefie...
