Description
Technical Field
The utility model relates to the technical field of ionosphere altimeters, in particular to a polymorphic antenna device for a mobile ionosphere altimeter.
Background
The ionosphere altimeter is used as main equipment for vertically observing the ionosphere on the ground, and provides important measurement data for the observation and research of the ionosphere. The whole ionosphere altimeter system generally comprises an antenna system, a high-frequency power amplifier, a signal processing system and an echo data analysis system (a software system, a hardware platform is a universal industrial personal computer).
The antenna system is divided into a transmitting antenna and a receiving antenna, and in order to measure the arrival angle and echo phase of a signal and separate an X wave and an O wave, a multi-path receiving antenna is often used. The following requirements must be met for an antenna for use with a altimeter system:
1) With a single vertical up narrow beam, without side lobes;
2) The frequency range must cover [1mhz,30mhz ], with consistent gain, circuit model and impedance over the frequency range;
3) The emission peak frequency is not less than 1kW, and has high efficiency;
4) The X wave and the O wave with elliptical polarization can be separated;
5) Antenna size (mainly height) is reduced as much as possible to reduce construction cost;
6) Since the transmitting antenna and the receiving antenna operate simultaneously, if transmitting and receiving are performed at the same place, the transmitting signal is easy to leak directly into the receiving circuit, resulting in overload of the receiving circuit.
Early ionosphere altimeters used large transmit (above 40 m) and receive antennas with a transceiver antenna area of 8000m 2 The above. The receiving antenna used by the current mainstream altimeter mainly comprises: (1) The CADI digital ionosphere altimeter developed in Canada adopts 4 mutually orthogonal active dipole antennas, ionosphere echo polarization information and arrival angle parameters are obtained by analyzing 4-channel signals received simultaneously, and the CADI antennas adopt the antenna scheme of triangular antennas. Wherein, the transmitting antenna adopts a double-line structure, the distance between the double lines is 0.5m, and 2 receiving antennas adopt a single-line structure; (2) The DPS-4D digital ionosphere altimeter in the United states adopts four orthogonal loop antenna arrays which are in the shape of regular triangles with 60m side length, wherein 3 antennas are positioned at 3 vertexes of the antenna array, and the other antenna is positioned at the center of the regular triangle antenna array, can receive electromagnetic wave magnetic field components and can distinguish normal waves and extraordinary waves of ionosphere echo. However, due to the large occupied area of the antennas, flexible station arrangement and mobile observation cannot be carried out according to research requirements, and along with the development of microelectronic and computer technologies, the modern digital altimeter is urgently required to develop towards the miniaturization of the antennas; (3) The antenna system of the PDI2 digital altimeter of the institute of geology and geophysics of China academy of sciences adopts a 1-transmission and 2-reception structure, namely adopts a double-line folded dipole antenna, wherein 1 transmitting antenna is high by 4-9m and has the length of 28m;2 receiving antennas are arranged in an orthogonal mode, the antenna height is 3.5-4m, the length is 28m, and the antenna field is about 1000m 2 。
In summary, the transceiver antenna system of the modern digital altimeter is still huge, and particularly the height of the transmitting antenna is generally above 30m, and the occupation area of the transceiver antenna is 1000m 2 Above can even reach 8000m 2 The device is complex to install, can only be used in some fixed observation stations, and cannot promote flexible station arrangement and mobile observation according to research needs; if a small transmitting antenna with a height of several meters is used, ionosphere frequency high-map observation data meeting scientific requirements is difficult to obtain.
While the radiation directions of the traveling wave Delta antenna, the dipole antenna, the T-shaped antenna and the triangular loop antenna can meet the vertical measurement requirement, the antenna is complex in erection and inconvenient to detach due to the fact that the antenna is large in size, can be used as a fixed station, and is not suitable for being used in a vehicle-mounted moving state.
In view of the above, the utility model provides a multi-state antenna system suitable for a mobile ionosphere altimeter, which has the advantages of simple structure, compact volume and convenient short-distance transportation and disassembly.
