Fly the needs of remote control, and wireless communication system needs the transmitting of normality, thus cannot by close wireless communication system or
Wirelessly communicate it is idle in the case of carry out electromagnetic field monitoring.
One, the design of airborne electromagnetic radiation monitor：For airborne electromagnetic radiation monitor usually there are two types of type, one kind is work
Frequency airborne electromagnetic radiation monitor, another kind are the airborne electromagnetic radiation monitoring instrument of radio frequency.
A can not have to the wireless communication system interference for worrying unmanned plane for power frequency airborne electromagnetic radiation monitor, because
Frequency phase-difference it is distant, wireless communication system does not affect the measurement of power frequency electromagnetic field.But the interfering frequency of motor is fallen
In the frequency range (5Hz-100kHz) of conventional power frequency airborne electromagnetic radiation monitor.Solution is：Using with
The power frequency electromagnet Field probe that 50Hz points electricity frequency measures function (is obtained using spectrum analysis function or is 50Hz by centre frequency
Narrow band filter obtains), this power frequency electromagnet Field probe can directly obtain the field strength of power frequency (50Hz), and avoid motor interference
Frequency range.Since the low frequency electromagnetic measurement demand of the overwhelming majority is in power domain, it is power frequency to need the frequency measured
(50Hz), therefore this scheme can solve the problems, such as this.
For B for the airborne electromagnetic radiation monitoring instrument of radio frequency, common electromagnetic measurement frequency range is 100kHz-6GHz, this
A frequency range is three dB bandwidth, but for the electric field of more than ten kHz frequency ranges, rejection ability limited (being usually 20dB) or energy
Induction, although smaller.But the interference field strength that generates of motor it is bigger such as common reached more than ten V/m, can be apparent
Influence emf probe measurement lower limit, and interference field strength caused by this motor is related with motor operating power
, that is to say, that it is interfered when motor speed is high big, interferes small when rotating speed is low, therefore cannot simply deduct interference
Signal.For this solution to the problem：Using the higher radio-frequency electromagnetic Field probe of measurement frequency lower limit, under measurement frequency
500kHz or measurement frequency lower limit are limited to as the radio-frequency electromagnetic Field probe of 30MHz (model probe needs special design).This
When probe 40dB or more can be reached for the rejection ability of the motor interference signal of more than ten kHz.
According to measurement demand, the demand of most of unmanned plane spatial electromagnetic field measurement comes from mobile communication base station (frequency
Range 800MHz-2.7GHz), broadcast and TV radiating station (working frequency 500kHz-800MHz), for the dry of wireless communication system
It disturbs, can be designed for the frequency of test object, the wireless communication system interfering frequency exclusion of unmanned plane itself is being measured
Except frequency.It is designed according to communication frequency used in unmanned plane；1) unmanned plane wireless communication frequency is 5.8GHz, is used
The lower radio-frequency electromagnetic Field probe of the measurement frequency upper limit, for example, by using upper frequency limit be 5.2GHz or the measurement frequency upper limit is
The emf probe of 3.5GHz.To avoid the interference of unmanned plane wireless communication system.2) for measurand working frequency with
Wireless communication frequency is close, can not be come effective the case where distinguishing, such as wireless communication frequency by Frequency Band Selection of popping one's head in
The unmanned plane of 2.45GHz, measurand are mobile communication base station (working frequency 800MHz-2.7GHz), it is difficult to from the frequency of probe
It is distinguished in rate selection, at this moment, following measures can be taken：If the antenna of multi-rotor unmanned aerial vehicle is normally at unmanned plane
On dry support arm, therefore by airborne electromagnetic radiation monitor, it is mounted on unmanned plane center, the upside of main part.It can incite somebody to action
The communication antenna designs of unmanned plane repack non-omnidirectional antenna into：It allows the master of unmanned plane antenna to penetrate direction to be designed as by unmanned plane
The heart is outwardly directed, and antenna episternites is made to reduce unmanned plane antenna to unmanned plane center (installation airborne electromagnetic towards unmanned plane center
Radiation monitor position) transmitting.
In this way, can usually make the interference field strength measured at airborne electromagnetic radiation monitor from original antenna (without setting
Meter or the omnidirectional antenna of repacking) interference field strength (1-2) V/m, (0.2-0.5) V/ is being dropped to using interference field strength after the program
M or less.Even the interference outside band, this is acceptable for electromagnetic environment measurement, radiates and supervises generally for airborne electromagnetic
The measurement lower limit requirement for surveying instrument is≤0.5V/m.
In summary it requires：Frequency for unmanned plane probe is preferably 500kHz-3.5GHz.
Two, airborne electromagnetic radiation monitor designs：1) there are two types of installation of the airborne electromagnetic radiation monitor on unmanned plane
Selection, one is mounted in the top of unmanned aerial vehicle body (main body), and one is mounted in the lower part of unmanned aerial vehicle body, but from unmanned plane
The angle of electromagnetic environment monitor, main radiation source (base station, power transmission and transformation line and radio and television launch facility) are all to be located in the air,
If mounted on the lower part of unmanned aerial vehicle body, it will appear signal before reaching airborne electromagnetic radiation monitor by unmanned plane machine
The problem of body blocks, and in underbelly, distance wireless communication system antenna closer to, it is easier to be interfered.Therefore will
Airborne electromagnetic radiation monitor is mounted on the top of unmanned plane；2) knot of airborne airborne electromagnetic radiation monitor and data collecting instrument

It is possible to reduce plus windage, however unmanned plane entirety flying quality (wind resistance, cruising ability and keep stability) can seriously by
