Abstract

The invention discloses a conformal active and passive radar guide head antenna cover. The conformal active and passive radar guide head antenna cover comprises a cover body, and further comprises a connecting ring assembly internally arranged in a cavity of the cover body, a plurality of conformal passive antennas arranged on the connecting ring assembly and an aerogel heat-insulating layer linked between the connecting ring assembly and the inner wall of the cover body, wherein the outer molded surfaces of the passive antennas are consistent with the inner molded surface of the cover body. The invention further provides a forming method for the antenna cover. The passive antennas and the antenna cover are designed in a conformal mode, and the passive antennas are peripherally and uniformly distributed on the connecting ring assembly inside the antenna cover, so that the homing angle range is great, the interior space of a guide head cabin is reduced, and guidance precision is improved; and the aerogel heat-insulating layer is adopted for insulating heat for the conformal passive antennas, so that normal use of antennas is guaranteed; and the conformal passive antennas are mountedon the connecting ring assembly, so that the structure is stable, and mounting is convenient.

Description

technical field [0001] The invention belongs to the technical field of radome, in particular to a conformal active and passive radar seeker radome and a forming method. Background technique [0002] The radar seeker is the core component of intercepting and tracking the radiation source. The active and passive radar seeker is an important form of radio compound homing technology, which is helpful for long-distance detection of targets with radiation sources, missile stealth and terminal precision. guidance. In the era of rapid development of aerospace technology and military industry, the active and passive radar seeker antenna conforms to a certain part of the missile body, which can effectively solve the problem of limited internal space of the missile radar seeker. The active and passive radar seeker system has improved the combat effectiveness of the new generation of medium and long-range air-to-air missiles. However, due to the limitations of the overall structure of ...
