It is wide.It can satisfy the air surveillance radar overwhelming majority frequency range within the scope of 100MHZ~8GHZ.Equipment standard configures frequency range
In 2~4GHZ.Suitable high-frequency amplifier and power divider, radio-frequency filter etc. is selected to can receive corresponding frequency as needed
Section, and replace simple and convenient.Second is that meeting various types antenna measurement.Including surface antenna, wire antenna, planar array antenna.Three
Be integrate it is portable.Detecting type small-power meter, frequency-selective amplifier, high-frequency amplifier, radio-frequency filter, power divider etc. are taken
Modularized design, radio frequency interface is unified general, is integrated in a cabinet, small in size, light-weight, structure is simple, convenient for taking
Band.Fourth is that meeting in interference and being measured on the position of complex electromagnetic environment.By using the switching of radio-frequency filter
It can measure, greatly reduce to the external electrical magnet ring to measurement in the weaker Frequency point of jamming power with frequency filtering selection
The requirement in border.
The utility model measurement parameter is more.Design mainly meets the measurement needs of antenna radiation pattern, gain, while can be with
Measurement bandwidth, polarization etc..Secondly easy to operate, measurement conveniently, meets sergeant cognitive ability.
Detailed description of the invention
Fig. 1 is the structural schematic block diagram of the utility model.
Specific embodiment
As shown in inside Fig. 1 dotted box, a kind of universal portable antenna measurement receiver connects including universal radio frequency
Mouth, wideband low noise amplifier, power divider, radio frequency power meter, RF switch, radio frequency detector device, radio-frequency filter group, choosing
Audio amplifier etc., the radio frequency interface are connected with tested antenna, and the wideband low noise amplifier will be for that will pass through radio frequency interface
The radiofrequency signal of access is amplified, and is sent to power divider, and radiofrequency signal is divided into two-way by the power divider, is sent all the way
Radio frequency power meter measurement obtains received signal power, and audio amplifier of in addition sending to be elected after radio frequency detector device detection all the way is shown
Show output.Radio-frequency filter group is accessed by RF switch before the radio frequency detector device, passes through two RF switch combination controls
The channel of radio-frequency filter group processed, to select to interfere the measurement for carrying out directional diagram after small Frequency point again.
Detailed process is: the radiofrequency signal that the tested antenna that radio frequency interface is sent into receives first being passed through low-noise amplifier
It amplifies, is divided into two-way by power divider, radio frequency power meter measurement is sent to obtain received signal power all the way, and then can be with
Carry out antenna gain or bandwidth, polarized measurement and calculating；In addition frequency of sending to be elected after radio frequency detector device detection all the way amplifies
