Abstract

The invention relates to a common-aperture broadband interferometer antenna array, which includes seven Vivaldi slot line antennas and a mounting plate; the mounting plate is a disc structure, and a round hole of Ф150 mm to 200 mm is opened at the eccentric position of the disc structure. ;The round hole is used to install infrared sensors or active antennas; seven Vivaldi slot line antennas are fixed on the surface of the disc structure, and the seven Vivaldi slot line antennas are arranged in a "cross" shape; where the "cross" shape crosses The slot line antenna is a common antenna, which is used for horizontal direction finding and pitch direction finding at the same time; the three horizontal slot line antennas are used for horizontal direction finding; the three vertical slot line antennas are used for pitch direction finding.

Description

technical field [0001] The invention belongs to the field of aerial common aperture broadband interferometer antenna. Background technique [0002] The passive radar seeker is a key component of anti-radiation weapons. The passive radar seeker has the advantages of long range, strong stealth ability, and all-weather all-weather. It has broad application prospects, but its accuracy is poor and its ability to resist bait interference The disadvantages such as poor performance and no anti-shutdown ability greatly restrict its application. Composite seeker can aim at the characteristics of passive radar seeker, use other guidance modes to make up for the defects of passive radar seeker, and achieve the effect of complementary advantages, which is one of the development trends of anti-radiation weapons. [0003] Traditional anti-radiation missile passive radar generally adopts four dual-arm planar helical antennas or zigzag arm antennas in order to achieve precise orientation, a...
