Optionally, the electronic device may also acquire the second frequency band signal.
102. And calculating a first average background noise power level value corresponding to the first frequency band signal at the maximum gain.
The method comprises the steps of automatically setting the maximum gain of the electronic device for first frequency band signals corresponding to each frequency band, calculating a first average background noise power level value of an average signal in the first frequency band signals, and recording the first average power level value (also referred to as the first average level value for short).
Optionally, the processing of the second frequency band signal by the electronic device may refer to the processing of the first frequency band signal, and is not described herein again.
103. And when the first average background noise power level value is larger than a preset target background noise power level value, automatically reducing the gain, and determining a first gain, wherein the first gain is smaller than the maximum gain.
When the electronic device obtains the first average background noise power level value, the first average background noise power level value is compared with a preset target background noise power level value (also referred to as a target level value for short). And when the first average background noise power level value is larger than a preset target background noise power level value, automatically reducing the gain, and determining a first gain, wherein the first gain is smaller than the maximum gain.
It can be understood that the electromagnetic background noise level values of the signals of the frequency bands are different, and the environments are also different. Wherein the gain is automatically reduced if the first average background noise power level value is greater than the target background noise power level value. For example, the reduced gain may be set to 3db, 5db, etc. in advance, and is not limited in particular.
Optionally, when the first average background noise power level value is smaller than a preset target background noise power level value, determining that the maximum gain is an available gain of the first frequency band signal, and adding the first average background noise power level value to the preset value to obtain a reference background noise power level value of the processing signal of the first frequency band signal of each frequency band.

106. And determining the first gain as the available gain of the first frequency band signal of each frequency band.
For the first frequency band signal, when the second average background noise power level value is smaller than the preset target background noise power level value, the first gain corresponding to the second average background noise power level value is the available gain of the first frequency band signal of each frequency band.

| electromagnetic environment assessment rating | First stage | Second stage | Three-stage | Four stages | Five stages |
| Corresponding gain under the condition of set target background noise power level value | Maximum gain of-3 db | Maximum gain of-6 db | Maximum gain of-9 db | Maximum gain of-12 db | Maximum gain of-15 db |

The signal gain and reference level can be used for signal processing in the electromagnetic spectrum detection.

It should be noted that steps 107-109 are optional steps.
In the embodiment of the invention, a first frequency band signal of each frequency band is obtained; calculating a first average background noise power level value corresponding to the first frequency band signal at the maximum gain; when the first average background noise power level value is larger than a preset target background noise power level value, automatically reducing the gain, and determining a first gain, wherein the first gain is smaller than the maximum gain; calculating a second average background noise power level value corresponding to the first frequency band signal when the first gain is achieved; when the second average background noise power level value is smaller than the preset target background noise power level value, adding the second average background noise power level value to a preset value to obtain a reference background noise power level value of the processing signal of the first frequency band signal of each frequency band; and determining the first gain as the available gain of the first frequency band signal of each frequency band. The available gain of the frequency band signals of each frequency band and the reference background noise power level value of the processing signal can be automatically set, so that the system resources are saved and the use convenience is improved.
In the multi-band signal automatic detection, the available gain and the reference background noise power level value (also referred to as reference level value for short) of each detection frequency band signal are not required to be manually set in advance, the frequency band signal is automatically sensed by a detection system, the available gain and the signal reference level value of each frequency band signal are set, and each frequency band signal and the whole electromagnetic environment are automatically evaluated.
Namely, the electronic device does not need to manually set the signal gain and the reference level of signal processing of each frequency band, thereby saving time and labor; especially, operators without specialized skills can operate complex signal detection work, such as a spectrum detection system of an unmanned plane. The competitiveness of the product is very good, because the user objects are often non-professional technicians. The operator can be prompted whether the current electromagnetic environment is good.

Secondly, the frequency band electromagnetic environment assessment grade data can be divided into five grades (first grade, second grade, third grade, fourth grade and fifth grade), no relevant national and industrial standards exist, the enterprise standards determine that the first grade is the best and is gradually reduced; the correspondence between the gain and the level is as shown in table 1 above. It should be noted that the five stages are only an example, and the specific setting may be determined according to actual requirements.
And setting the gain to be the maximum gain value of the local machine one by one according to the frequency band data.
Then, the gain values of the frequency band are set one by one as the current gain value minus the preset decrement value until the background noise level value of the frequency band is less than or equal to the preset target level value.
And then, comparing the electromagnetic environment evaluation grade data described in the table 1, and giving the current electromagnetic environment grade data of the gain value corresponding to the frequency band. It should be noted that, the above corresponding steps are performed one by one to obtain electromagnetic environment evaluation grade data of each frequency band.
Further, after each frequency band is evaluated, comparing the comprehensive electromagnetic situation evaluation grade data to obtain a comprehensive electromagnetic situation evaluation grade, wherein the comprehensive electromagnetic situation evaluation grade data does not have international or industrial standards and is determined by the enterprise standard, and the data is shown in the table 2 and is not repeated here.
And finally, prompting the user of the obtained electromagnetic environment evaluation grade data by voice or characters. And after the electromagnetic situation is sensed, performing model processing by using the determined available gain values and reference level values of each frequency band during automatic scanning detection.
It should be noted that the available gain value (i.e. the gain set last) of each frequency band is recorded by a variable and the target level value is added by 5-6db according to experience, i.e. the reference level value for signal detection.
In the embodiment of the invention, in the frequency band scanning detection, the available gain of each frequency band signal and the reference level of a processing signal are automatically set instead of manually; electromagnetic situation description of each frequency band and an overall electromagnetic situation evaluation method; to prompt the user with voice or text that 'good electromagnetic environment' is good, that 'bad electromagnetic environment is common, that is, the detection place' is recommended to be changed.
