[0002] Synthetic Aperture Radar (SAR) systems are two-dimensional high-resolution imaging radars that can operate globally in all weather conditions and around the clock for Earth observation. Furthermore, the information acquired by SAR systems is two-dimensional target imaging information of the ground or objects. Therefore, the amount of image information collected by SAR systems is enormous and requires a large amount of storage space.

[0003] Currently, data is transmitted in real time using data transmission systems to save storage space in SAR systems. However, since the bandwidth of SAR systems is much larger than that of data transmission systems, when SAR and data transmission systems operate on the same frequency band, communication signals may interfere with the signals of SAR systems, resulting in lower data quality acquired by SAR systems. At the same time, the signals of SAR systems may also overwhelm the signals of data transmission systems due to their high power, resulting in lower data transmission integrity and timeliness.

[0057] This specification may use the phrases “in one embodiment,” “in another embodiment,” “in yet another embodiment,” or “in other embodiments,” all of which may refer to one or more of the same or different embodiments according to this application.

[0058] Firstly, to facilitate understanding of this application, a communication method provided in this application will be described in detail. Furthermore, the communication method of this application embodiment is applied in the scenario of "acquiring image data of the ground or objects using Synthetic Aperture Radar (SAR), and then transmitting the acquired image data to the target system or target device through a communication system". It is worth noting that in the following embodiments, the data acquisition system is a SAR system and the data transmission system is a communication system.

[0059] like Figure 1 The diagram shown is a flowchart of a communication method provided in an embodiment of this application, which specifically includes steps S101-S103.

[0060] S101, determine the data acquisition duration and the first data transmission duration.

[0061] Here, the data acquisition duration refers to the time it takes for the data acquisition system to collect image data of the ground or objects in a certain area. This data acquisition duration is determined based on the attribute parameters of the data acquisition system and the acquisition parameters set by the user.

[0062] As one example, when determining the data acquisition duration, the beamwidth, operating distance, and operating speed of the data acquisition system are obtained. Then, the data acquisition duration is calculated using the beamwidth, operating distance, and operating speed. Alternatively, the data acquisition duration can be calculated using the following formula (1).

[0063]

[0064] Among them, T sys Indicates the data collection duration, Θ az R represents the beamwidth. c V represents the effective distance. sar θ represents the running speed, and θ represents the oblique angle.

[0065] Here, the beamwidth is the horizontal beamwidth relative to the aircraft's operating conditions. It's worth noting that all of the above parameters can be manually set, meaning they can be adjusted based on actual needs, operating environment, etc.

[0066] Similarly, the first data transmission duration is the duration during which the data transmission system maintains data transmission. Optionally, when determining the first data transmission duration, attribute information of the data transmission system is obtained, wherein the attribute information includes at least the bandwidth, frequency, and antenna length of the data transmission system, so as to determine the first data transmission duration based on the attribute information.

[0067] S102, based on the current ratio determined by the data acquisition duration and the first data transmission duration, determine the communication mode, wherein the communication mode includes time-domain discontinuity mode and frequency-domain discontinuity mode.

[0068] After determining the data acquisition duration and the first data transmission duration, the current ratio is determined based on the data acquisition duration and the first data transmission duration. Optionally, the current ratio can be determined by referring to the following formula (2).

[0069]

[0070] Where η represents the current ratio, T sys T0 represents the duration of data collection, and T0 represents the duration of the first data transmission.

[0071] Here, the communication mode includes time-domain discontinuity mode and frequency-domain discontinuity mode. That is, the communication mode can be determined as either time-domain discontinuity mode or frequency-domain discontinuity mode. Optionally, after determining the current ratio, it is further determined whether the current ratio falls within the ratio range. If the current ratio falls within the ratio range, the communication mode is determined to be time-domain discontinuity mode; if the current ratio does not fall within the ratio range, the communication mode is determined to be frequency-domain discontinuity mode.

[0072] The ratio range in this embodiment is greater than 0 and less than or equal to 10. Of course, in specific implementations, any standard value within this ratio range, such as 10, can also be used. After determining the current ratio, the current ratio is compared with the standard value. If the current ratio is less than or equal to the standard value, the communication mode is determined to be a time-domain discontinuity mode; if the current ratio is greater than the standard value, the communication mode is determined to be a frequency-domain discontinuity mode. This embodiment does not impose specific limitations on this aspect.

[0073] S103 performs data communication based on communication mode.

[0074] After determining whether the communication mode is time-domain discontinuous mode or frequency-domain discontinuous mode, data communication is performed based on the communication mode. The following sections describe the steps for data communication when the communication mode is time-domain discontinuous mode and the steps for data communication when the communication mode is frequency-domain discontinuous mode.

[0075] Figure 2 A flowchart of a method for data communication based on a communication mode is shown when the communication mode is a time-domain discontinuous mode, which specifically includes steps S201-S204.

[0076] S201, determine the first bandwidth.

[0077] S202, based on the amount of data to be transmitted and the first bandwidth, determine the second data transmission duration.

[0078] S203, determine the first interruption ratio based on the first data transmission duration and the second data transmission duration.

[0079] S204, data communication is performed based on the data acquisition duration and the first interruption ratio.

[0080] In this embodiment, the frequency points used for communication, i.e., data transmission, in each region have a fixed range. For example, communication is performed in a certain frequency band, and there are N frequency points in that band, namely f1...f N One or more frequency points can be selected for communication. Furthermore, the bandwidth corresponding to each frequency point is also set to a fixed range, such as B. com,1 ......B com,M , where f1......f nFor frequencies with relatively small bandwidths, the corresponding bandwidth range is 1MHz-10MHz; f n ......f N This refers to a frequency point with a relatively large bandwidth, corresponding to a bandwidth range of 10MHz-100MHz. Of course, both the frequency point and bandwidth can be set according to actual needs.

[0081] As one example, when the communication mode is time-domain discontinuity mode, one or more frequency points are determined from the frequency band corresponding to the current area to ensure that the SAR system can communicate normally with the ground system or equipment. Furthermore, when multiple frequency points are determined, the frequency point closest to the SAR center carrier frequency is preferred as the communication frequency point. Then, the maximum bandwidth within the bandwidth range corresponding to the communication frequency point is determined as the first bandwidth.

[0082] Further, the second data transmission duration is determined based on the amount of data to be transmitted and the first bandwidth. Optionally, a first communication rate is calculated using the first bandwidth and the signal-to-noise ratio, wherein the first communication rate is the maximum communication rate allowed by the data transmission system. Then, the second data transmission duration is calculated using the amount of data to be transmitted and the first communication rate.

[0083] As one example, the first communication rate is determined by the following formula (3).

[0084] C max =B max log2(1+S / N) (3)

[0085] Among them, C max B represents the first communication rate. max S represents the first bandwidth, and S / N represents the signal-to-noise ratio.

[0086] Here, the signal-to-noise ratio is the ratio between the transmitted signal and the noise signal, and its value ranges from greater than or equal to 1000 to less than or equal to 3000, preferably 1000.

[0087] After obtaining the first communication rate, the second data transmission duration is determined by the following formula (4).

[0088]

[0089] Among them, T com Q represents the duration of the second data transmission, Q represents the amount of data to be transmitted, and C represents the amount of data to be transmitted. max This indicates the first communication rate.

[0090] After obtaining the second data transmission duration, a first discontinuity ratio is determined based on the first and second data transmission durations. Optionally, the first discontinuity ratio can be calculated using the following formula (5).

[0091]

[0092] Where γ represents the first discontinuity ratio, T0 represents the first data transmission duration, and T com This indicates the duration of the second data transmission.

[0093] In practical implementation, given the duration of the second data transmission, the duration difference between the first and second data transmission durations can be calculated using the first discontinuity ratio. For data acquisition systems such as SAR systems, the first discontinuity ratio is the proportion of time intervals between synthesizing one image data point. The value of this first discontinuity ratio is greater than 0 and less than or equal to 0.2.

[0094] After obtaining the first discontinuity ratio, data communication is performed based on the data acquisition duration and the first discontinuity ratio. As one example, the runtime of the data acquisition system and the data transmission system is determined based on the first discontinuity ratio.

[0095] Optionally, the time required for the data transmission system to transmit data, i.e. the third data transmission time, can be calculated using the following formula (6).

[0096] T sar,1 =γT sys (6)

[0097] Among them, T sar,1 T represents the duration of the third data transmission, γ represents the first discontinuity ratio, and T represents the duration of the third data transmission. sys Indicates the duration of data collection.

[0098] At this time, the data acquisition system collects data for a duration of T. sar,2 =(1-γ)T sys The third data transmission duration serves as the duration for data transmission by the data transmission system. This helps to prevent interference between the signals of the data acquisition system and the data transmission system, thereby improving data quality, data integrity, and timeliness.

[0099] Figure 3 A flowchart of a method for data communication based on a communication mode is shown when the communication mode is frequency domain discontinuity mode, which specifically includes steps S301-S303.

[0100] S301, using the amount of data to be transmitted and the duration of the first data transmission, calculate the second communication rate.

[0101] S302, determine the second bandwidth based on the second communication rate and signal-to-noise ratio.

[0102] S303 performs data communication based on the second bandwidth and the filtering coefficient.

[0103] In specific implementation, when calculating the second communication rate using the amount of data to be transmitted and the first data transmission duration, the following formula (7) can be used as a reference.

[0104]

[0105] Among them, C min Q represents the second communication rate, Q represents the amount of data to be transmitted, and T0 represents the first data transmission duration.

[0106] After calculating the second communication rate, the second communication rate and signal-to-noise ratio are calculated using the following formula (8) to obtain the second bandwidth.

[0107]

[0108] Among them, B min Indicates the second bandwidth, C min S represents the second communication rate, and S / N represents the signal-to-noise ratio.

[0109] Here, the second bandwidth is the maximum bandwidth that the data transmission system can transmit data, and at the same time, it is the minimum bandwidth occupied by the data acquisition system. When the bandwidth corresponding to the data transmission system accounts for the smallest proportion of the bandwidth corresponding to the data acquisition system, the frequency domain discontinuity ratio of the data acquisition system is the smallest, the amount of discontinuous information is small, and thus the recovery of missing signals can be achieved.

[0110] Based on this, the corresponding communication frequency and the second bandwidth can be determined based on the current region for data transmission.

[0111] In practical implementation, to ensure that the bandwidth corresponding to the data transmission system can meet the data transmission requirements, a band-stop filter is added before data transmission to provide sufficient bandwidth for data transmission. Specifically, the second bandwidth can be adjusted based on the filter coefficients of the band-stop filter, as shown in formula (9), to obtain the communication bandwidth for data transmission.

[0112] B filter =kB min (9)

[0113] Among them, B filter B represents the communication bandwidth, k represents the filtering coefficient, and B represents the filtering coefficient. min This indicates the second bandwidth.

[0114] The filtering coefficient is the threshold coefficient for the transmitted signal of the data acquisition system. Depending on the actual system operation, the value of the filtering coefficient can be greater than 1 and less than or equal to 1.4, or a value that can be allowed by the actual system operation to provide sufficient bandwidth for communication.

[0115] The embodiments of this application can determine the current communication mode in real time based on the data acquisition duration and the first data transmission duration, so as to carry out data communication based on the communication mode, that is, to transmit the acquired data, thereby avoiding mutual interference between the signals of the data acquisition system and the signals of the data transmission system, improving the data quality and the integrity and timeliness of data transmission.

[0116] Based on the same inventive concept, the second aspect of this application also provides a communication device corresponding to the communication method.
