It should be understood that such data can be interchanged where appropriate so that the embodiments of the utility model described herein can be implemented in orders other than those illustrated or described herein.

[0021] Figure 1 A schematic diagram of a phase scanning positioning device provided in an embodiment of this utility model is shown below. Figure 1As shown, the phase-scan positioning device includes: a control module 101, a radio frequency low-noise amplifier module 102, a filter module 103, a position positioning module 104, a first antenna 105, and at least one second antenna 106; the position positioning module 104 is connected to the first antenna 105 and is used to acquire the azimuth angle of the phase-scan positioning device; the radio frequency low-noise amplifier module 102 is connected to the second antenna 106 and is used to receive the wireless signal of the target terminal and perform channel selection and signal amplification; the input terminal of the filter module 103 is connected to the first antenna 105 of the radio frequency low-noise amplifier module 106. One output terminal is connected to the first input terminal of the RF low-noise amplifier module 102; the filter module 103 is used to split and filter the signal of the selected channel; the first terminal of the control module 101 is connected to the position positioning module 104, and the second terminal of the control module 101 is connected to the RF low-noise amplifier module 102; the control module 101 is used to obtain the position of the target terminal based on the wireless signal of the target terminal after signal amplification and the azimuth angle of the phase scanning positioning device itself; the first output terminal of the control module 101 is connected to the control terminal of the RF low-noise amplifier module 102.

[0022] Specifically, the location positioning module 104 receives signals through the first antenna 105 to obtain the latitude and longitude of the phase-scanning positioning device itself, and calculates the azimuth angle of the device to avoid positioning deviations caused by the lack of device attitude reference. The location positioning module 104 is used to provide the spatial reference angle of the phase-scanning positioning device itself, eliminating geometric positioning errors. Optionally, the location positioning module 104 includes a GNSS positioning module. The location positioning module 104 receives GNSS satellite signals through the first antenna to obtain the azimuth angle of the phase-scanning positioning device itself. The first antenna 105 includes a GNSS satellite positioning antenna.

[0023] The radio frequency low-noise amplifier module 102 receives the target terminal signal through the second antenna 106, then performs frequency band channel selection and low-noise amplification on the processed signal. Multi-band processing is applied to the signal. Optionally, the second antenna 106 includes a directional scanning antenna array.

[0024] The filtering module 103 receives the signal after selecting a channel from the RF low-noise amplifier module 102, splits the signal into multiple channels, and performs independent bandpass filtering on each channel. Single-channel filtering after signal splitting by the filtering module 103 improves isolation during filtering. For example, the filtering module 103 includes a six-band combiner. After receiving the signal from the RF low-noise amplifier module 102, the filtering module 103 splits the signal into multiple channels according to different frequency bands and filters the signals. Optionally, the signal can be divided into the following frequency bands: 700MHz, 1.8GHz, 2.1GHz, 3GHz, 4GHz, and 5GHz. The specific frequency division method is not limited further. Single-channel filtering after signal splitting by the filtering module 103 avoids the severe crosstalk problem of multi-band signals during signal filtering.

[0025] The filtering module 103 sends the filtered signal to the RF low-noise amplifier module 102 through its output. The RF low-noise amplifier module 102 amplifies the split and filtered signal. The RF low-noise amplifier module 102 then sends the amplified signal to the control module 101.

[0026] The control module 101 receives the device azimuth data sent by the location positioning module 104 and the amplified and filtered wireless signal of the target terminal sent by the radio frequency low noise amplification module 102 to obtain the location of the target terminal.

[0027] In the phase-scan positioning device provided in this embodiment, the device eliminates reference errors by outputting the device azimuth angle through the position positioning module. The radio frequency low-noise amplifier module includes channel selection and signal amplification functions, and the filtering module performs splitting and single-channel filtering to suppress frequency band crosstalk. Finally, the control module calculates the terminal position based on the phase difference algorithm. This phase-scan positioning device avoids positioning distortion caused by multi-band signal crosstalk, improves positioning accuracy in complex electromagnetic environments, and supports multi-band parallel processing.

[0028] Based on the above embodiments, Figure 2 A schematic diagram of another phase scanning positioning device provided in an embodiment of this utility model is shown below. Figure 2 As shown, the filtering module 103 includes: the input terminal of the filtering module 103 is connected to the first output terminal of the RF low noise amplifier module 102 through two channels; the output terminal of the filtering module 103 is connected to the first input terminal of the RF low noise amplifier module 102 through six channels.

[0029] Specifically, the input of the filtering module 103 is connected to the first output of the RF low-noise amplifier module 102 via two channels. The RF low-noise amplifier module 102 receives the wireless signal from the target terminal through the second antenna 106, which carries two signals. These two signals are then transmitted through the two channels between the filtering module 103 and the RF low-noise amplifier module 102.

[0030] For example, the two signals include: a main lobe direct signal and a side lobe reflected signal. The main lobe direct signal is the undistorted component of the electromagnetic wave directly transmitted to the target terminal. The side lobe reflected signal is the scattered wave component after reflection by environmental objects. The main lobe direct signal and the side lobe reflected signal have a phase difference, which allows the spatial angle of the target terminal to be calculated.

[0031] The filtering module 103 performs single-channel filtering on the wireless signal of the target terminal. When filtering the wireless signal of the target terminal, the filtering module 103 divides the wireless signal according to different frequency bands, and each channel is filtered individually. The filtered signal from each channel is transmitted to the RF low-noise amplifier module 102 through six channels between the output of the filtering module 103 and the first input of the RF low-noise amplifier module 102. Optionally, the filtering module 103 includes a six-frequency combiner.

[0032] Based on the above embodiments, Figure 3 A schematic diagram of another phase scanning positioning device provided in an embodiment of this utility model is shown below. Figure 3 As shown, the second terminal of the control module 101 is connected to the RF low-noise amplifier module 102 through at least one pair of channels; the number of channel pairs is equal to the number of antennas 106. The second output terminal of the control module 101 is connected to the RF low-noise amplifier module 102 through at least one pair of channels.

[0033] Specifically, the signal acquired by the RF low-noise amplifier module 102 through the second antenna 106 includes at least two signals: the main lobe direct signal and the side lobe reflection signal. The azimuth angle of the target terminal can be obtained through the main lobe direct signal and the side lobe reflection signal. Therefore, the second end of the control module 101 is connected to the RF low-noise amplifier module 102 through at least one pair of channels; the number of channel pairs is equal to the number of second antennas 106. After amplifying the signal filtered by the filtering module 103, the RF low-noise amplifier module 102 sends each signal to the control module 101 through its corresponding channel. In each pair of channels, one channel sends the main lobe direct signal, and the other channel sends the side lobe reflection signal.

[0034] The second output of the control module 101 is connected to the RF low-noise amplifier module 102 via at least one pair of channels. The control module 101 sends a calibration signal to the RF low-noise amplifier module 102 through its second output. Optionally, there are two calibration signals: one is a 4G (fourth-generation mobile communication and related technologies) signal, and the other is a 5G (fifth-generation mobile communication) signal. Further, one signal can be a 4G LTE (Long Term Evolution) signal, and the other a 5G NR (New Radio) signal. The two calibration signals have a known theoretical phase difference. After the control module 101 sends the calibration signal to the RF low-noise amplifier module 102, the RF low-noise amplifier module 102 transmits and receives the signal via the second antenna 106. The control module 101 then determines the phase difference based on the received calibration signal and compares it with the known theoretical phase difference, performing calibration according to the error.

[0035] Based on the above embodiments, Figure 4 A schematic diagram of another phase scanning positioning device provided in an embodiment of this utility model is shown below. Figure 4 As shown, the control module 101 includes a channel selection unit 1011 and a data calculation unit 1012; the first input terminal of the data calculation unit 1012 is connected to the first terminal of the control module 101, the second input terminal of the data calculation unit 1012 is connected to the second terminal of the control module 101, and the output terminal of the channel selection unit 1011 is connected to the output terminal of the control module 101; the data calculation unit 1012 is used to obtain the position of the target terminal based on the amplified wireless signal of the target terminal and the azimuth angle of the phase scanning positioning device itself, and the channel selection unit 1011 is used to select the transmission channel of the radio frequency low noise amplification module 102.

[0036] Specifically, the channel selection unit 1011 of the control module 101 controls the channel selection of the RF low-noise amplifier module 102, receiving data from each channel. For example, the channel selection unit 1011 analyzes the data congestion status in real time to output a channel switching command. Simultaneously, the number of channel switching positions of the channel selection unit 1011 is related to the connection relationship between the second terminal of the control module 101 and the RF low-noise amplifier module 102. The number of switching positions of the channel selection unit 1011 is greater than or equal to the number of connections between the second terminal of the control module 101 and the RF low-noise amplifier module 102.

[0037] The data calculation unit 1012 performs positioning calculations. The position of the target terminal is obtained based on the magnified wireless signal of the target terminal and the azimuth angle of the phase-scan positioning device itself.

[0038] Optionally, the channel selection unit 1011 includes an FPGA chip or logic circuit, and the channel selection unit 1011 has the characteristic of fast response. The data calculation unit 1012 can be a multi-core processor to perform fast and complex calculations.

[0040] Specifically, the multi-channel switching unit 1021 switches channels according to control commands to select the target frequency band channel. The multi-channel switching unit 1021 can select the channel of the RF low-noise amplifier module 102 as needed to send the wireless signal of the target terminal to the filtering module 103 or send the amplified wireless signal of the target terminal to the control module 101.

[0041] The multi-band low-noise amplifier unit 1022 receives and amplifies the filtered wireless signal from the target terminal sent by the filtering module 103. The filtering module 103 performs splitting and filtering on the wireless signal from the target terminal; therefore, the multi-band low-noise amplifier unit 1022 can amplify these filtered signals. Optionally, the multi-band low-noise amplifier unit 1022 combines the amplified multiple signals.

The output terminal of the multi-channel switching unit is connected to the control terminal of the multi-band low-noise amplifier unit, and the input terminal of the multi-band low-noise amplifier unit is connected to the first input terminal of the RF low-noise amplifier module. The RF low-noise amplifier module achieves dynamic frequency band selection through the multi-channel switching unit and performs frequency-band optimized amplification using the multi-band low-noise amplifier unit. This avoids mutual interference between multi-band signals, improving sensitivity and anti-interference capability.

[0044] Specifically, the splitter unit 1031 distributes the signal. Its input is directly connected to the first output of the RF low-noise amplifier module 102. For example, the splitter unit uses a splitter circuit to divide the input signal into six independent channels.

[0045] The filtering unit 1032 consists of six independent bandpass filters, each corresponding to a branch channel.
