Description
Technical field
The invention belongs to aviation Shared aperture Broadband interferometer field of antenna.
Background technology
Passive Radar Seeker is the critical component on anti-radiation weapon, Passive Radar Seeker have operating distance remote,
The advantages such as stealth capabilities is strong, round-the-clock is round-the-clock, have broad application prospects, but its low precision, anti-bait interference performance
Difference and not there is the shortcomings such as anti-shutoff capability make it apply to be very restricted.Multi-mode seeker can be for passive radar
The characteristic of target seeker, utilizes other guided modes to make up Passive Radar Seeker defect, reaches the effect having complementary advantages, is anti-spoke
One of development trend penetrating weapon.
Tradition antiradiation missile passive radar in order to realize accurate pointing, general use four both arms flat helical antennas or
Sinuous Antenna form, its system complex, cost is high.Flat helical antenna volume is big, Heavy Weight, if to ensure antenna simultaneously
Directivity and field range, it is desirable to the bore of antenna is at least greater than half-wavelength.In multi-mode seeker, often space chi
Very little the most extremely limited, flat helical antenna is to be difficult to meet using of multi-mode seeker require, therefore, it is necessary to use new sky
Line and layout type carry out complete design.
Summary of the invention
The purpose of the present invention: propose a kind of Shared aperture Broadband interferometer antenna array
Technical scheme:
There is provided a kind of Shared aperture Broadband interferometer antenna array, including seven Vivaldi slotline antennas and installing plate；Installing plate
For disc structure, and have the circular hole of Ф 150mm～200mm at the eccentric position of this disc structure card；This circular hole is used
In installation infrared sensor or active antenna；Seven Vivaldi slotline antennas are fixed in this disc structure card, and seven
The arrangement of Vivaldi slotline antennas is " ten " font；Wherein the slotline antennas of " ten " font infall is common antenna, this shared sky
Line is simultaneously used for horizontal direction finding and pitching direction finding；3 horizontal slotline antennas are for horizontal direction finding；3 longitudinal slotline antennas
For pitching direction finding.
In the horizontal antenna array of 3 horizontal slotline antennas and common antenna composition, the spacing between each antenna is
80～225mm；In the Longitudinal Antenna row of 3 longitudinal slotline antennas and common antenna composition, the spacing between each antenna
It is 60～186mm.
