Description
Technical field
The present invention relates to Radar Antenna System field, specially a kind of butterfly radar antenna.
Background technology
Through-wall imaging radar can carry out non-intrusion type detection to covering over the object within the walls, especially as ultra-wideband radar technology
Rapid development, the realization of high-resolution, remote, portable through-wall imaging radar are progressively possibly realized.Some domestic engineerings are surveyed
Spy department, institute and university successively deploy to study to ultra-wideband radar technology, and successively introduce the countries such as the U.S., Canada
ULTRA-WIDEBAND RADAR product, achieve rapid progress.Due to China to ultra-broadband wall-through imaging radar technology research starting compared with
Evening, weighting and theoretical research, so accelerating development the development and commercialization of ultra-broadband wall-through imaging radar, to hostage's rescue, instead
Probably stability maintenance etc. has important application value and realistic meaning, a subsystem of the antenna as ultra-broadband wall-through imaging radar system
System, is responsible for converting the electrical signal to electromagnetic wave Net long wave radiation, it is also desirable to the echo from target is converted into electric signal and passed to
The sampling system of radar receiver.For the ultra-broadband wall-through imaging radar of time domain impulse system, the performance of antenna not only embodies
On frequency domain characteristic, while it is also embodied on time domain specification.The quality of the time domain specification of antenna, directly affect the spy of radar system
Survey performance.Due to the dispersion interaction of wall, the interference of multiple scattering body, the limitation such as RCS of target, it is desirable to which antenna has

The antenna of inanimate object detection has impedance loading butterfly antenna, TEM electromagnetic horns and Vivaldi antennas.Impedance loading butterfly day
The planar structure of line is advantageous to the coupling of antenna and medium, can effectively eliminate the secondary reflection of antenna end.Impedance loads butterfly
The radiation efficiency of shape antenna is typically poor, is only solved by improving the impulse amplitude of emitter.TEM electromagnetic horns and
Vivaldi antenna gains are higher, and directionality is preferable, but antenna to a certain extent all be present and not so good ask is coupled with metope
Topic, and general volume is larger, is unfavorable for the portable design of system.The application scenario of overall balance through-wall imaging radar and property
It can require, one or more of which antenna can be selected.However, time domain specification and the impedance of current impedance loading butterfly antenna
Bandwidth still needs to further improve, and the range resolution ratio of through-wall imaging radar is also required to further improve such as Application No.
201420307542.9 utility model patent, although further being improved to the range resolution ratio of wall imaging radar, working as has
During larger wind, the fixation to the device can not be accomplished, cause the device to be scraped by strong wind, and the device can only be at one
Direction reception signal can not be comprehensive reception signal.
