Wherein, the interference strength refers to the strength of the interference signal detected by the electronic device. The stronger the interference strength is, the more the interference of the interference signal to the electronic device is, and the electronic device may not accurately implement navigation. The interference direction is the direction of the interference source of the interfering signal. The interferer type is the type to which the interferer of the interfering signal belongs. The interference source types may specifically include natural interference sources and man-made interference sources.

In one embodiment, as shown in fig. 10, performing interference detection on the current environment to obtain an interference state parameter includes:

step 1002, obtaining target characteristic information of a target radio frequency parameter, where the target radio frequency parameter is generated when the signal processing circuit performs signal processing on the satellite positioning signal, and the target characteristic information is obtained by performing signal processing on the received target satellite positioning signal through the signal processing circuit.

Wherein the target radio frequency parameters include, but are not limited to, at least one of signal description parameters and hardware state parameters of the satellite positioning signals when decoded into navigation messages. Wherein the signal description parameter is used to represent a signal state of the satellite positioning signal. The hardware state parameter is used to represent a hardware state of the signal processing circuit. Optionally, the target rf parameters include, but are not limited to, PGA (Programmable Gain Amplifier) Gain, IQ (In-phase Quadrature) SIGNAL level, snr (SIGNAL-to-NOISE RATIO), nf (NOISE level, NOISE floor), CN0 (carrier-to-NOISE RATIO), NoiseFloor, BaseBand Amplitude, and the like, and the embodiment is not limited thereto. In the listed target rf parameters, signal interference of the satellite positioning signal affects the listed target rf parameters, so that a specific interference result can be determined. The target satellite positioning signal refers to a satellite positioning signal received by the signal processing circuit and can be understood as a satellite positioning signal to be detected as an interference result. The target characteristic information may be used to represent a change condition of the target rf parameter, and may also be used to represent a specific parameter value of the target rf parameter, which is not limited in this embodiment. The target radio frequency parameter is generated when the signal processing circuit performs signal processing on the satellite positioning signal, and the target characteristic information is used for representing the change condition of the target radio frequency parameter or representing the specific parameter value of the target radio frequency parameter, so that the target characteristic information can reflect the interference result of the target satellite positioning signal to a certain extent.

Specifically, when the signal processing circuit receives a target satellite positioning signal and performs signal processing, the signal processing circuit generates a target radio frequency parameter to obtain target characteristic information, and the electronic device obtains the target characteristic information obtained by processing the target satellite positioning signal by the signal processing circuit.

And 1004, performing interference detection on the target satellite positioning signal according to the target characteristic information to obtain an interference result of the target satellite positioning signal, wherein the interference result comprises an interference state parameter.

Because the target characteristic information can reflect the interference result of the target satellite positioning signal to a certain extent, the electronic device can perform interference detection on the target satellite positioning signal according to the target characteristic information, so as to obtain the interference result of the target satellite positioning signal, wherein the interference result comprises the interference state parameter.

According to the technical scheme of the embodiment, the target satellite positioning signal is subjected to interference detection through the target characteristic information of the target radio frequency parameter generated when the signal processing circuit performs signal processing on the target satellite positioning signal, so that the interference result of the target satellite positioning signal is obtained, the problem that how the interference of the satellite positioning signal cannot be determined in the related technology is solved, and the interference result of the satellite positioning signal is determined.

In one possible embodiment, the obtaining target characteristic information of the target radio frequency parameter includes:

acquiring a plurality of parameter values corresponding to target radio frequency parameters output by a signal processing circuit, wherein the plurality of parameter values are obtained by signal processing of target satellite positioning signals by the signal processing circuit; at least one parameter value is selected from the plurality of parameter values as target characteristic information.

At least one parameter value is selected from the plurality of parameter values as target characteristic information, namely the target characteristic information comprises one or more parameter values. The term "plurality" means two or more. If at least two parameter values are selected from the plurality of parameter values as the target feature information, at least two consecutive parameter values may be used as the target feature information.

It should be noted that the target satellite positioning signal may be a satellite positioning signal that is continuously received, and the signal processing circuit processes the satellite positioning signal once every pair to obtain one parameter value, and then the signal processing circuit processes the satellite positioning signal that is continuously received to obtain a plurality of parameter values.

In this embodiment, the number of parameter values included in the target characteristic information may be related to the expected interference result. Wherein the interference result can be used to represent, but is not limited to, at least one of: whether the target satellite positioning signal generates signal interference, the time when the signal interference occurs, whether the interference disappears, the time when the interference disappears, the interference direction, the type of the interference source, the frequency band of the interference, the interference strength, and the like.

In general, the interference of the target satellite positioning signal may be a single tone noise interference or a broadband noise interference. The single-tone noise interference is interference with obvious peak value of interference signal, and is represented as spike with personality. Specifically, the interference signal generating the single-tone noise interference may fall within a certain satellite constellation, may fall between two adjacent satellite constellations, may fall before the signal processing circuit, and may also exist in at least two cases. The broadband noise interference means that the interference signal spectrum has no obvious peak value and is integrally represented as a burr without individuality. Specifically, the interference signal generating the broadband noise interference may fall into a certain satellite constellation, may fall between two adjacent satellite constellations, may fall before the signal processing circuit, and may also exist in at least two cases.

The following embodiments further describe how to obtain the interference result of the target satellite positioning signal based on any of the above embodiments.

In one embodiment, as shown in FIG. 11, the interference detection for the target satellite positioning signal according to the target characteristic information includes steps 1102 to 1108.

Step 1102, determining the variation amplitude of the target radio frequency parameter according to the target characteristic information.

Wherein, the variation amplitude is used for representing the variation magnitude of the target radio frequency parameter. Generally, the larger the variation amplitude of the target radio frequency parameter is, the larger the variation of the target radio frequency parameter is; the smaller the variation amplitude of the target radio frequency parameter is, the smaller the variation of the target radio frequency parameter is.

In one possible embodiment, the target characteristic information includes at least two parameter values of the target rf parameter, so that the variation range of the target rf parameter is determined according to the at least two parameter values. In particular, the variation amplitude may be a difference between two adjacent parameter values of the at least two parameter values.

And 1104, judging whether the variation amplitude is higher than a preset amplitude.

In this embodiment, if the variation range is higher than the predetermined range, step 1106 is executed. Optionally, if the variation amplitude is not higher than the preset amplitude, the step 1102 is executed again.

And step 1106, acquiring a target variation trend of the target radio frequency parameter, wherein the target variation trend is a variation trend of the target radio frequency parameter when the variation amplitude is higher than a preset amplitude.

In this embodiment, if the variation range is higher than the preset range, the target variation trend of the target rf parameter is obtained. Optionally, the target variation trend may be increased or decreased, which is determined according to the actual situation when performing interference detection, and this embodiment is not limited.

And 1108, determining that the signal interference occurs or disappears in the target satellite positioning signal according to the target change trend.

In this embodiment, the target satellite positioning signal may generate signal interference when the target radio frequency parameter increases, and the target satellite positioning signal may generate signal interference and disappear when the target radio frequency parameter decreases; the target change trend may be that signal interference occurs in the target satellite positioning signal when the target radio frequency parameter decreases, and signal interference disappears in the target satellite positioning signal when the target change trend is that the target radio frequency parameter increases, which is related to the specific characteristic of the target radio frequency parameter, and this embodiment is not limited.

According to the technical scheme, the target change trend of the target radio frequency parameter is obtained only when the change amplitude is higher than the preset amplitude, so that signal interference or signal interference disappearance of the target satellite positioning signal is determined according to the target change trend, the problem of high calculation power caused by interference detection always through the target change trend is solved, and resources required by interference detection are reduced.

In one possible embodiment, the target satellite positioning signal is a high-frequency signal, the signal processing circuit includes a signal conversion module and a sampling module, the signal conversion module is configured to convert the target satellite positioning signal into an intermediate-frequency signal, the sampling module is configured to sample the intermediate-frequency signal to obtain a sampled signal level, the target radio frequency parameter includes the sampled signal level, and it is determined that the target satellite positioning signal has signal interference or disappears according to a target variation trend, the method includes: if the target change trend is that the level of the sampling signal is increased, signal interference occurs in the target satellite positioning signal; and if the target variation trend is that the level of the sampling signal is reduced, the signal interference of the target satellite positioning signal disappears. The target satellite positioning signal generates signal interference, namely the interference strength is interference; and when the signal interference of the target satellite positioning signal disappears, the interference intensity is switched to be non-interference.

The target satellite positioning signal in this embodiment is a carrier signal, and therefore the target satellite positioning signal is a high frequency signal. The intermediate frequency signal may be an IQ signal. The IQ signal is an in-phase quadrature signal, I is in-phase, Q is quadrature, and the phase difference between the IQ signal and I is 90 degrees. The sampling module samples the IQ signal to obtain a sampling signal level corresponding to the IQ signal.

In this embodiment, if there is signal interference in the target satellite positioning signal, the level of the sampling signal is increased; if the signal interference of the target satellite positioning signal disappears, the level of the sampling signal is reduced, so that whether the target satellite positioning signal generates the signal interference or the signal interference disappears can be determined according to the change trend of the level of the sampling signal.

In one possible embodiment, the target rf parameter includes a sampling gain of the sampling module, the sampling gain is used to maintain a stable level of the sampled signal, and the target satellite positioning signal is determined to have signal interference or have no signal interference according to the target variation trend, including: if the target variation trend is that the sampling gain is reduced, the target satellite positioning signal generates signal interference; and if the target variation trend is that the sampling gain is increased, the signal interference of the target satellite positioning signal disappears.

In this embodiment, if there is signal interference in the target satellite positioning signal, the sampling signal level will increase, and at this time, in order to keep the sampling signal level stable, the sampling gain will decrease; if the signal interference of the target satellite positioning signal disappears, the sampled signal level decreases, and at this time, the sampling gain increases in order to keep the sampled signal level stable. Therefore, whether the target satellite positioning signal is in a signal interference condition or in a signal interference disappearance condition can be determined through the variation trend of the sampling gain.

In one possible implementation, the target radio frequency parameters include a sampled signal level and a sampled gain. In this embodiment, if the target trend is that the sampled signal level increases and the sampling gain decreases, the target satellite positioning signal generates signal interference; if the target variation trend is that the sampled signal level is reduced and the sampling gain is increased, the signal interference of the target satellite positioning signal disappears.

In one possible embodiment, the target rf parameters include a first target rf parameter and a second target rf parameter, the first target rf parameter being related to the second target rf parameter; the method for detecting the interference of the target satellite positioning signal according to the target characteristic information to obtain the interference result of the target satellite positioning signal comprises the following steps: and determining an interference result of the target satellite positioning signal according to the first target characteristic information and the second target characteristic information, wherein the first target characteristic information is the target characteristic information of the first target radio frequency parameter, and the second target characteristic information is the target characteristic information of the second target radio frequency parameter.

According to the technical scheme of the embodiment, the interference result of the target satellite positioning signal is determined through the target characteristic information corresponding to the plurality of target radio frequency parameters, so that the accuracy of interference detection is higher.

In one embodiment, as shown in FIG. 12, determining the interference result of the target satellite positioning signal according to the first target characteristic information and the second target characteristic information includes steps 1202 to 1206.

Step 1202, determining a first change condition of a first target radio frequency parameter according to the first target characteristic information.

The first change condition is the change condition of the first target radio frequency parameter determined according to the first target characteristic information. In this embodiment, the first target characteristic information includes a plurality of parameter values, and the first variation may be determined according to a plurality of consecutive parameter values in the first target characteristic information.

And 1204, determining a second change condition of the second target radio frequency parameter according to the second target characteristic information.

The second change condition is the change condition of the second target radio frequency parameter determined according to the second target characteristic information. In this embodiment, the second target characteristic information includes a plurality of parameter values, and the second variation may be determined according to a plurality of consecutive parameter values in the first target characteristic information.

And step 1206, determining the interference strength of the target satellite positioning signal due to signal interference according to the first change situation and the second change situation.

In the embodiment, the first variation situation and the second variation situation are combined together to determine the interference strength of the target satellite positioning signal with the signal interference.

In one possible embodiment, the target satellite positioning signal is a high-frequency signal, the signal processing circuit includes a signal conversion module and a sampling module, the signal conversion module is configured to convert the target satellite positioning signal into an intermediate-frequency signal, the sampling module is configured to sample the intermediate-frequency signal to obtain a sampling signal level, the first target radio frequency parameter is the sampling signal level, the second target radio frequency parameter is a sampling gain of the sampling module, and the sampling gain is used to maintain a stable sampling signal level.

Specifically, when positioning is performed according to a target satellite positioning signal, the target satellite positioning signal generally needs to be converted from a high-frequency signal to an intermediate-frequency signal through a signal conversion module in the signal processing circuit, and then the intermediate-frequency signal is sampled through a sampling module to obtain a sampling signal level, so that positioning is performed according to a sampling result. During the sampling process, in order to ensure the safety of the sampling module, the level of the C sampling signal is kept stable by adjusting the sampling gain.

In the embodiment, the sampling signal level is used as a first target radio frequency parameter, and the sampling gain is used as a second target radio frequency parameter, so that the interference result of the target satellite positioning signal is determined according to the first variation situation of the sampling signal level and the second variation situation of the sampling gain.

It can be understood that the first target rf parameter and the second target rf parameter of this embodiment may also be other rf parameters, as long as the rf parameters are generated when the signal processing circuit performs signal processing on the satellite positioning signal and can reflect whether the satellite positioning signal has signal interference, and this embodiment is not limited.

In the following embodiments, one of the sampled signal levels and one of the sampled gains are exemplified.

Referring to fig. 13, fig. 13 is a schematic diagram illustrating the relationship between the IQ signal level and the PGA gain and the satellite positioning signal when the interference signal is stable according to an embodiment of the present invention. Wherein the IQ signal level is one of the sampled signal levels. The PGA gain is one of the sampling gains. When analog signals in the signal processing circuit are converted into digital signals, the greater the PGA gain is, the greater the IQ signal level is; the smaller the PGA gain, the smaller the IQ signal level. The PGA gain can dynamically adjust the IQ signal level to keep the IQ signal level within the effective range of the sampling module. In an ideal environment, the PGA gain and IQ signal level are stable and invariant.

As shown in fig. 13, when several interference signals are stable, the IQ signal level is increased instantaneously when the interference signals enter the circuit along with the target satellite positioning signal, thereby triggering the PGA gain to decrease, and the IQ signal level decreases after the gain decreases. After the removal of the interference signal, the level of the IQ signal is instantaneously decreased, thereby triggering the gain of the PGA to increase, and then the level of the IQ signal is increased.

However, as the interference signal increases, the gain decreases continuously within the gain control range, and the IQ signal level fluctuates up and down within a predetermined signal interval but is limited. The interference signal continues to increase and exceeds the gain control range, the PGA gain reaches the lower limit of the range, and the signal level rises. The interference signal continues to increase, and the IQ signal level will eventually reach the upper limit of the interval of the preset signal interval.

The above is the basic principle of interference detection, and of course, in practical cases, the radio frequency parameters include not only PGA gain and IQ signal level, but also signal-to-noise ratio, noise floor level, and the like, and the principle is similar and will not be discussed much here.

In one possible embodiment, the interference strength includes at least one of a primary interference, a secondary interference and a tertiary interference, and the determining the interference strength of the signal interference of the target satellite positioning signal according to the first variation and the second variation includes:

if the first change condition is that the signal fluctuation value of the sampling signal level in the preset signal interval is lower than the preset fluctuation value, and the second change condition is that the sampling gain is continuously reduced in the gain regulation range, the target satellite positioning signal generates first-level interference;

if the first change condition is that the signal fluctuation value of the sampling signal level in the preset signal interval is higher than or equal to the preset fluctuation value, and the second change condition is that the sampling gain is continuously located at the lower limit of the range of the gain regulation range, the target satellite positioning signal generates secondary interference;

if the first change condition is that the sampling signal level is continuously located at the upper limit value of the interval of the preset signal interval, and the second change condition is that the sampling gain is continuously located at the lower limit value of the range of the gain regulation range, the target satellite positioning signal generates three-level interference.

In the embodiment, by studying the relationship change between the IQ signal level and the PGA gain and the satellite positioning signal, the interference result of the target satellite positioning signal is determined according to the first change situation of the IQ signal level and the second change situation of the PGA gain.

According to the technical scheme of the embodiment, the interference result of the target satellite positioning signal is determined according to the first change condition of the IQ signal level and the second change condition of the PGA gain, excessive calculation is not needed, and resources needed for determining the interference result are reduced.

It can be understood that, in this embodiment, the interference result of the satellite positioning signal may also be determined by using other radio frequency parameters, as long as the relation change between the radio frequency parameter and the satellite positioning signal is studied, and the specific radio frequency parameter for determining the interference result is not limited in this embodiment.

It should be noted that, in this embodiment, at least one interference intensity may be selectively detected according to needs, and the specific interference intensity that needs to be detected is not limited in this embodiment.

In one embodiment, as shown in fig. 14, the interference detection on the target satellite positioning signal according to the target characteristic information to obtain the interference result of the target satellite positioning signal includes steps 1002 to 1004.

Step 1402, obtaining a target mapping relationship, where the target mapping relationship represents a relationship between the characteristic information and the interference information.

Wherein the interference information comprises at least one of an interference frequency and an interference strength. Specifically, if the interference information includes an interference frequency, the target mapping relationship is a relationship between the feature information and the interference frequency.
