It manages device 14 to be electrically connected, a wherein output end for processor 14 is electrically connected with Frequency Band Selection filter module 13.
In the utility model embodiment, it can not also include pitch angle control motor 113, but control the precision of angle
Precision in the case where controlling motor 114 including pitch angle control motor 113 and azimuth simultaneously is high.Antenna 111 and frequency
It can not also be connected by slip ring 12 between section selection filter module 13, but antenna received signal can be transmitted using other
Mode to Frequency Band Selection filter module 13 connects.Slip ring 12 can not also be passed through between cradle head controllor 112 and processor 14
Connection, but connected in such a way that other can be transmitted signal between cradle head controllor 112 and processor 14.Slip ring 12
Effect be continuous rotation while to guarantee that the route that transmits downwards and frequency spectrum cable are not twisted disconnected.Antenna 111 can be full frequency band
Wide band LPDA.
In the utility model embodiment, Frequency Band Selection filter module 13 may include the received letter of input terminal receiving antenna
Number the first frequency range selector 131, output termination processor 14 the second frequency range selector 132 and be serially connected in the first Frequency Band Selection
The bandpass filter of multiple and different frequency ranges between device 131 and the second frequency range selector 132, a wherein output end for processor 14
It is also electrically connected respectively with the first frequency range selector 131 and the second frequency range selector 132, in parallel between multiple bandpass filters, frequency
Section selection filter module 13 can also be straight between the first frequency range selector 131 and the second frequency range selector 132 including being serially connected in
Circulation passage 138.Multiple bandpass filters can specifically include the first bandpass filter 133, the second bandpass filter 134, third
Bandpass filter 135, the 4th bandpass filter 136 and the 5th bandpass filter 137, naturally it is also possible to including above-mentioned 5 band logicals
Any combination of filter, wherein the first bandpass filter 133 can be 5.8GHz bandpass filter, the second bandpass filter
134 can be 2.4GHz bandpass filter, and third bandpass filter 135 can be 915MHz bandpass filter, the filter of the 4th band logical
Wave device 136 can be 845MHz bandpass filter, and the 5th bandpass filter 137 can be 450MHz bandpass filter.Due to
5.8GHz high frequency signal attenuation is bigger, needs to amplify 5.8GHz signal, therefore the input terminal of 5.8GHz bandpass filter is also
It is in series with 5.8GHz amplifying circuit 139, since 2.4GHz high frequency signal attenuation is bigger, needs to amplify 2.4GHz signal, because
The input terminal of this 2.4GHz bandpass filter is also in series with 2.4GHz amplifying circuit 140.
The working principle of unmanned aerial vehicle arrangement for detecting provided by the embodiment of the utility model is as follows:
Processor 14 says the word by the route that slip ring 12 connects to cradle head controllor 112, starts to detect, cradle head controllor
112 execute order, and control pitch angle control motor 113 and azimuth control motor 114 are rotated by command mode, while in real time
Azimuth and pitch angle information and antenna received spectrum signal processor 14 is transferred to downwards in real time by slip ring 12, processing
Device 14 controls multiple discrete bandpass filters, to filter out interference of other frequency ranges to detecting frequency range, in unmanned plane frequency spectrum
When detecting, according to locating detecting frequency range, processor 14 passes through the first frequency range selector 131 of control and the second frequency range selector
132, it is switched on the bandpass filter of frequency range corresponding with reception, realizes the purpose of bandpass filtering, filter out one outside this frequency range
Clutter and interference are cut, the anti-interference ability of equipment is improved.Filtering out interference by bandpass filter enables the distance for detecting unmanned plane
Enough farther, the actual azimuth that sends in conjunction with cradle head controllor 112 and pitch angle information are so as to knowing the side of unmanned plane
Parallactic angle and pitch angle.
The spectrum signal that antenna receives will also be handled by Frequency Band Selection filter module 13, and detailed process is as follows:
Firstly, being transmitted to frequency range choosing through slip ring 12 with the spectrum signal that antenna 111 receives a certain azimuth and pitch angle
Select filter module 13；When selecting 5.8GHz to receive signal processing, the signal received from antenna 111 is passed through the by processor 14
The selection of one frequency range selector 131 and the second frequency range selector 132 to electric signal, selection have the access of 5.8GHz bandpass filter
On, since 5.8GHz high frequency signal attenuation is bigger, need to amplify 5.8GHz signal, then to the filter of signal 5.8GHz
Wave, final output signal are handled to processor 14；When selecting 2.4GHz to receive signal processing, processor 14 is from antenna
111 signals received have by the selection of the first frequency range selector 131 and the second frequency range selector 132 to electric signal, selection
On the access of 2.4GHz bandpass filter, since 2.4GHz high frequency signal attenuation is bigger, need to amplify 2.4GHz signal, so
Afterwards to the filtering of signal 2.4GHz, final output signal is handled to processor 14；It is received at signal in selection 915MHz
When reason, the signal received from antenna 111 is passed through the first frequency range selector 131 and the second frequency range selector 132 by processor 14
Selection to electric signal, selection have on the access of 915MHz bandpass filter, since the decaying of 915MHz frequency signal is smaller, no
It needs to amplify 915MHz signal, the directly filtering to signal 915MHz, final output signal is handled to processor 14；
When selecting 845MHz to receive signal processing, the signal received from antenna 111 is passed through the first frequency range selector by processor 14
131 and second selection of the frequency range selector 132 to electric signal, selection have on the access of 845MHz bandpass filter, due to
The decaying of 845MHz frequency signal is smaller, does not need to amplify 845MHz signal, the directly filtering to signal 845MHz, finally
Processor 14 is outputed signal to be handled；When selecting 450MHz to receive signal processing, processor 14 receive from antenna 111
The signal arrived has 450MHz band by the selection of the first frequency range selector 131 and the second frequency range selector 132 to electric signal, selection
On the access of bandpass filter, since the decaying of 450MHz frequency signal is smaller, do not need to amplify 450MHz signal, directly to this
The filtering of signal 450MHz, final output signal are handled to processor 14；If on these frequencies, not can choose straight
Circulation passage 138, since the loss of the first frequency range selector 131 and the second frequency range selector 132 is in the range that can be detected,
Different spectrum signals can be received in the case where not increasing antenna；Finally, the spectrum signal received is transferred to processing
Device 14 is handled.
In the utility model unmanned aerial vehicle arrangement for detecting, due to including the frequency range choosing being connected between antenna and processor
Filter module is selected, a wherein output end for processor is also electrically connected with Frequency Band Selection filter module.Therefore it is detected in unmanned aerial vehicle
In, corresponding different frequency range is effective done by Frequency Band Selection filter module using what the bandpass filter of corresponding frequency band filtered out outside band
It disturbs.Anti-interference ability of the unmanned aerial vehicle arrangement for detecting under strong electromagnetic is greatly improved, it can be normal under complex electromagnetic environment
It uses.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
