To this end, ES equipment includes a digital receiver that measures signal characteristics (frequency, pulse width, pulse arrival time, pulse signal strength) at high speed in high-density signal environments. The digital receiver operates the reception bandwidth based on the onboard signal collection plan, collects signals, and measures their characteristics. At this time, the receiver characteristics and the frequency ranges used by other equipment must be taken into account.

There is a problem in that the receiver characteristics and frequency ranges used by other equipment for generating the signal acquisition plan must be manually reflected by the user, and the structure of these receiver characteristics and frequency ranges is dependent on the equipment on which the signal acquisition plan generator is installed or the equipment on which the receiver is installed.

[0006] There is a problem in that receiver characteristics and frequency ranges used by other equipment, which must be manually reflected by the user, change frequently during development or use, and reflecting them requires a significant amount of effort and time.

[0007] A signal acquisition plan generation device implemented based on receiver characteristics dependent on the equipment to which the device is installed or the equipment to which the receiver is installed, and the frequency range structure used by other equipment, has the problem that it is difficult to reuse when developing similar equipment in the future.

[0008] There is a need for research and development of technology capable of adaptively generating signal acquisition plans in response to the operating characteristics of digital receivers and external devices. Prior art literature

[0036] Various embodiments of the signal acquisition plan generation device and method according to the present invention will be described in detail below with reference to the attached drawings.

[0037] The embodiments described in this specification may be applied to electronic warfare equipment that operates a receiving bandwidth based on a signal acquisition plan, but are not necessarily limited thereto, and may be applied to various communication fields that receive or acquire signals.

[0041] The signal information input unit (110) can receive a target signal list containing signal characteristic information of the collected target signal and first operation characteristic information of the receiver. The signal information input unit (110) can further receive second operation characteristic information of an external device.

[0042] The external device may be a device that operates in conjunction with or in conjunction with the signal collection plan generating device (100) or the receiver, and may be a communication device operated in an electronic warfare environment that is the same as or similar to the electronic warfare environment in which the signal collection plan generating device (100) operates. The external device may be one of another signal collection plan generating device, receiver, transmitter, or jammer, or a combination thereof.

[0043] The first operational characteristic information may include receiver characteristics, such as the frequency usage range of the receiver.

[0046] Frequency duty can refer to the ratio of the time spent in the ON state to the time spent in the OFF state. For example, if the duty ratio is 50%, the time spent in the ON state and the time spent in the OFF state can be equal.

[0047] The reception band determining unit (120) can determine at least one signal reception possible section based on the first operation characteristic information. The reception band determining unit (120) can determine the signal reception possible section by further considering the second operation characteristic information.

[0048] The reception plan generation unit (130) can generate a signal reception plan for a target signal by determining at least one reception bandwidth based on signal characteristic information among the signal reception possible intervals.

[0049] When there is only one signal to be collected, the reception plan generation unit (130) can determine the band corresponding to the frequency band of the signal to be collected among the signal reception possible intervals as the reception planned bandwidth.

[0050] When there are multiple signals to be collected, the reception plan generation unit (130) can determine frequency bands corresponding to each of the multiple signals to be collected among the signal reception possible intervals as the reception planned bandwidth.

[0051] The generated signal reception plan may include information regarding the planned reception bandwidth for operation.

[0052] Not all blocks shown in FIG. 1 are essential components, and in other embodiments, some blocks connected to the signal acquisition plan generating device (100) may be added, changed, or deleted.

[0053] FIG. 2 is a flowchart illustrating a signal acquisition plan generation method performed in a signal acquisition plan generation device according to an embodiment of the present invention.

[0054] In step S210, the signal information input unit (110) can receive a target signal list containing signal characteristic information of the collected target signal and first operation characteristic information of the receiver.

[0055] In step S220, the receiving band determining unit (120) can determine at least one signal receiving range based on the first operation characteristic information.

[0056] In step S230, the reception plan generation unit (130) can generate a signal reception plan for a target signal by determining at least one reception bandwidth based on signal characteristic information among the signal reception possible intervals.

[0057] The generated reception bandwidth can be matched with information regarding signals to be received through the reception bandwidth and included in a signal reception plan. The target signals for collection that match the reception bandwidth may be signals whose frequency band is completely included within the reception bandwidth, as well as signals whose frequency band is at least partially included.

[0058] FIG. 3 is a flowchart illustrating a signal acquisition plan generation method performed in a signal acquisition plan generation device according to another embodiment of the present invention.

[0059] Referring to FIG. 3, in step S310, the signal information input unit (110) can receive a target signal list containing signal characteristic information of the target signal to be collected, first operation characteristic information of the receiver, and second operation characteristic information of the external device.

[0060] In step S320, the receiving band determining unit (120) can determine at least one signal receiving range based on the first operation characteristic information and the second operation characteristic information.

[0061] Step S320 is explained in more detail through Fig. 4.

[0062] In step S330, the reception plan generation unit (130) can generate a signal reception plan for a target signal by determining at least one reception bandwidth based on signal characteristic information among the signal reception possible intervals.

[0063] Step S330 is explained in more detail through FIGS. 8 and 9.

[0064] FIG. 4 is a flowchart for explaining in more detail the signal reception range determination step illustrated in FIG. 3.

[0065] Referring to FIG. 4, in step S321, the receiving band determining unit (120) can determine whether the frequency duty of the external device is greater than or equal to a predetermined reference value. If the frequency duty of the external device is not greater than or equal to the predetermined reference value, the receiving band determining unit (120) can proceed to step S322, and if the frequency duty of the external device is greater than or equal to the predetermined reference value, the receiving band determining unit (120) can proceed to step S323.

[0066] In step S322, the receiving band determining unit (120) can determine the frequency usage range of the receiver as the signal reception possible range.

[0067] In step S323, the receiving band determining unit (120) can determine the frequency usage section of the receiver, excluding the frequency usage section of the external device, as the signal reception possible section.

[0068] Information about the external device can be included in the signal reception plan by matching it to the signal reception range that overlaps at least partially with the frequency usage range of the external device.

[0069] FIG. 5 is a diagram showing exemplary data of a signal reception possible interval determined based on the received first operation characteristic information and second operation characteristic information received by a signal collection plan generating device according to an embodiment of the present invention, and the received first operation characteristic information and second operation characteristic information.

[0070] FIG. 6 is a diagram showing frequency ranges corresponding to the first operation characteristic information and the second operation characteristic information of FIG. 5.

[0071] FIG. 7 is a diagram showing a signal reception range determined based on the first operation characteristic information and the second operation characteristic information of FIG. 5.

[0072] First, referring to FIG. 6, reference numeral 611 of FIG. 6 represents the frequency usage interval 1 of the receiver, which is the first operation characteristic information shown through FIG. 5, ranging from 1.8 GHz to 7 GHz.

[0073] Reference numeral 612 represents the frequency usage section 2 of the receiver, which is the first operation characteristic information shown in FIG. 5, ranging from 6.8 GHz to 10 GHz.

[0074] The reception band determining unit (120) can determine the frequency usage section of the receiver as a signal reception possible section. If there are multiple frequency usage sections of the receiver, the reception band determining unit (120) can determine the signal reception possible section by sequentially checking the multiple frequency usage sections. For example, if the second frequency usage section is completely included in the first frequency usage section, the signal reception possible section corresponding to the second frequency usage section may not be created because the signal reception possible section corresponding to the first frequency usage section has already been created. If the second frequency usage section is not included in the first frequency usage section, the reception band determining unit (120) can determine the signal reception possible section corresponding to the second frequency usage section.

[0075] Here, the second frequency usage interval being completely included in the first frequency usage interval may mean that the minimum value of the second frequency usage interval is greater than the minimum value of the first frequency usage interval, and the maximum value of the second frequency usage interval is smaller than the maximum value of the first frequency usage interval.

[0076] Reference numeral 621 represents the frequency usage range of external device 1, which is the second operation characteristic information shown in FIG. 5, ranging from 2 GHz to 2.2 GHz.

[0077] Reference numeral 622 represents the frequency usage range of external device 2, which is the second operation characteristic information shown in FIG. 5, ranging from 3 GHz to 4 GHz.

[0078] The receiving band determining unit (120) can determine the signal receiving range by excluding the frequency usage range of the external device from the signal receiving range that is pre-generated through the frequency usage range of the receiver or the frequency usage range of the receiver.

[0079] The receiving band determining unit (120) can determine the signal receiving range by excluding the frequency usage range of the external device from the signal receiving range generated in advance through the frequency usage range of the receiver or the frequency usage range of the receiver when the frequency duty is greater than or equal to a predetermined reference value (e.g., 70%).

[0080] When the frequency duty is less than a predetermined reference value (e.g., 70%), the receiving band determining unit (120) can generate a signal receiving range without excluding the frequency usage range of the external device from the frequency usage range of the receiver or the signal receiving range generated in advance through the frequency usage range of the receiver.

[0081] As explained in more detail through FIGS. 5 to 7, external device 1, which is the second operation characteristic information shown in FIG. 5, has a frequency duty cycle of 50%, so the frequency usage range of the receiver is determined as the signal reception range without excluding the range corresponding to the frequency usage range of external device 1, which is 2 GHz to 2.2 GHz, from the frequency usage range 1 of the receiver, which is 1.8 GHz to 7 GHz.

[0082] External device 2, which is the second operation characteristic information shown in Fig. 5, has a frequency duty cycle of 100%, so the signal reception range is determined by excluding the range corresponding to the frequency usage range of external device 2, which is 3 GHz to 4 GHz, from the frequency usage range 1 of the receiver, which is 1.8 GHz to 7 GHz.

[0083] Referring to FIG. 7, the receiving band determining unit (120) can determine signal reception ranges corresponding to reference numerals 701, 702, and 703 based on the first operation characteristic information and the second operation characteristic information shown through FIG. 5.

[0084] The interval corresponding to the signal reception range 1 corresponding to reference numeral 701 and the signal reception range 2 corresponding to reference numeral 702 is the interval corresponding to the frequency usage range of external device 2, which is 3 GHz to 4 GHz, where the frequency duty is greater than or equal to a predetermined reference value.

[0085] FIG. 8 is a flowchart for explaining in more detail the step of determining the bandwidth to be received in FIG. 3 and generating a signal reception plan for the target signal to be collected.

[0086] Referring to FIG. 8, in step S331, the reception plan generation unit (130) can determine whether the frequency band of the signal to be collected is greater than or equal to the maximum reception bandwidth of the receiver. If the frequency band of the signal to be collected is greater than or equal to the maximum reception bandwidth of the receiver, the reception plan generation unit (130) may proceed to step S332. If the frequency band of the signal to be collected is not greater than or equal to the maximum reception bandwidth of the receiver, the reception plan generation unit (130) may proceed to step S333.

[0087] In step S332, the reception plan generation unit (130) can divide the frequency band of the signal to be collected into multiple frequency bands. The reception plan generation unit (130) can then perform step S333.

[0088] In step S333, the reception plan generation unit (130) can determine the band corresponding to the frequency band of the signal to be collected among the signal reception possible intervals as the reception planned bandwidth.

[0089] FIG. 9 is a flowchart for explaining in more detail another embodiment of the step of determining the bandwidth to be received in FIG. 3 and generating a signal reception plan for a target signal to be collected.

[0090] Referring to FIG. 9, in step S334, the reception plan generation unit (130) can determine whether the frequency bands of a plurality of target signals to be collected overlap at least partially. If the frequency bands of a plurality of target signals to be collected overlap at least partially, the reception plan generation unit (130) can proceed to step S335, and if the frequency bands of a plurality of target signals to be collected do not overlap, the reception plan generation unit (130) can proceed to step S337.

[0091] In step S335, the reception plan generation unit (130) can determine whether the merged frequency band does not exceed the maximum reception bandwidth of the receiver even if multiple collection target signals with overlapping frequency bands are merged. If the merged frequency band does not exceed the maximum reception bandwidth of the receiver even if multiple collection target signals with overlapping frequency bands are merged, the reception plan generation unit (130) may proceed to step S336. If the merged frequency band exceeds the maximum reception bandwidth of the receiver when multiple collection target signals with overlapping frequency bands are merged, the reception plan generation unit (130) may proceed to step S337.

[0092] In step S336, the reception plan generation unit (130) can determine a merged frequency band by merging frequency bands of multiple target signals that have overlapping frequency bands.

[0093] In step S337, the reception plan generation unit (130) can determine frequency bands corresponding to each of the multiple target signals to be collected among the signal reception possible intervals as the reception planned bandwidths.

[0094] In step S338, the reception plan generation unit (130) can determine the section corresponding to the merged frequency band among the signal reception possible sections as the reception planned bandwidth.

[0095] The operations of the reception plan generation unit (130) described through FIG. 9 may be performed in succession to the operations of the reception plan generation unit (130) described through FIG. 8, but are not necessarily limited thereto, and the operations of the reception plan generation unit (130) described through FIG. 9 may be performed individually from the operations of the reception plan generation unit (130) described through FIG. 8.

[0096] Although FIGS. 2 to 4 and FIGS. 8 to 9 describe each process being executed sequentially, this is merely an illustrative description, and a person skilled in the art may modify and adapt the process in various ways without departing from the essential characteristics of the embodiments of the present invention, such as changing the order described in FIGS. 2 to 4 and FIGS. 8 to 9, executing one or more processes in parallel, or adding other processes.

[0097] FIG. 10 is a diagram showing exemplary data of a signal collection plan generating device according to an embodiment of the present invention, including first operation characteristic information received by the device, signal characteristic information of a signal to be collected, and signal characteristic information of a signal to be collected determined based on the signal characteristic information of the signal to be collected.

[0098] Referring to FIG. 10, the first operation characteristic information may include information regarding the maximum width of the receiver's receiving bandwidth.

[0100] Reference numeral 1111 in Fig. 11 represents the interval corresponding to 2 GHz to 7.5 GHz, which is an exemplary signal collection range shown in Fig. 10.

[0101] Reference numeral 1101 indicates the interval corresponding to the frequency band of the target signal A shown in FIG. 10, which is 1.8 GHz to 2.2 GHz.

[0102] Reference numeral 1102 indicates the interval corresponding to the frequency band of the target signal B shown in FIG. 10, which is 2.6 GHz to 3.1 GHz.

[0103] Reference numeral 1103 indicates the interval corresponding to the frequency band of the target signal C shown in FIG. 10, which is 2.8 GHz to 3.4 GHz.

[0104] Reference numeral 1104 indicates the interval corresponding to the frequency band of the target signal D shown in FIG. 10, which is 6.5 GHz to 8.3 GHz.

[0105] FIG. 12 is a diagram showing the frequency band of a signal to be collected divided into a plurality of frequency bands according to one embodiment of the present invention.

[0106] The reception plan generation unit (130) can divide the frequency band of the signal to be collected into multiple frequency bands when the frequency band of the signal to be collected is larger than the maximum reception bandwidth of the receiver. The reception plan generation unit (130) can determine the frequency bands corresponding to each of the multiple frequency bands divided within the signal reception range as the scheduled reception bandwidth.

[0107] Referring to FIG. 11, the frequency band of the target signal D corresponding to reference numeral 1104 is 6.5 GHz to 8.3 GHz, which exceeds the maximum reception bandwidth of the receiver, 800 MHz. Therefore, the reception plan generation unit (130) can divide the target signal D into multiple parts to determine the planned reception bandwidth.

[0108] The reception plan generation unit (130) can divide a target signal to be collected that exceeds the maximum reception bandwidth of the receiver into multiple signals having a size corresponding to the maximum reception bandwidth of the receiver. For example, the reception plan generation unit (130) can divide a target signal to be collected that exceeds the maximum reception bandwidth of the receiver into multiple signals that are smaller by the maximum reception bandwidth of the receiver or by a predetermined reference size (e.g., 0.05 GHz) smaller than the maximum reception bandwidth of the receiver.

[0109] The reception plan generation unit (130) can divide the frequency band of the signal to be collected into multiple frequency bands such that at least some of them overlap when the frequency band of the signal to be collected is larger than the maximum width of the reception bandwidth of the receiver.

[0110] When the reception plan generation unit (130) divides a target signal that is larger than the maximum reception bandwidth of the receiver, it can divide the target signal that is larger than the maximum reception bandwidth of the receiver into multiple frequency bands such that the target signal overlaps by a value obtained by multiplying the maximum reception bandwidth of the receiver by a predetermined reference ratio (e.g., 0.3).

[0111] Referring to FIG. 12, the reception plan generation unit (130) can divide the collected target signal D (1104) into signals Da, Db, and Dc such that they overlap by a value obtained by multiplying the maximum reception bandwidth (0.8 GHz) by a predetermined reference ratio (0.3).

[0112] Reference numeral 1104-1 indicates the interval corresponding to the frequency band of the target signal Da, which is 6.5 to 7.293 GHz.

[0113] Reference numeral 1104-2 indicates the interval corresponding to the frequency band of the target signal Db, which is 7.053 to 7.846 GHz.

[0114] Reference numeral 1104-3 indicates the interval corresponding to the frequency band of the target signal Dc, which is 7.606 to 8.3 GHz.

[0115] FIG. 13 is a drawing showing the expected reception bandwidth according to one embodiment of the present invention.

[0116] Fig. 13 explains how to determine the intended reception bandwidth corresponding to the examples in Figs. 10 to 12.

[0117] Reference numeral 1301 is the planned reception bandwidth corresponding to the target signal A. The frequency band of the target signal A is 1.8 GHz to 2.2 GHz, but since the signal reception range is 2 GHz to 7.5 GHz, the range corresponding to the frequency band of the target signal within the signal reception range, which is 2 GHz to 2.2 GHz, can be determined as the planned reception bandwidth.

[0118] The reception plan generation unit (130) can determine a merged frequency band by merging the frequency bands of multiple target signals that overlap at least partially, and when the frequency bands of multiple target signals that overlap at least partially do not exceed the maximum reception bandwidth of the receiver, the merged frequency bands of multiple target signals that overlap at least partially do not exceed the maximum reception bandwidth of the receiver. The merged frequency band can be determined as the reception planned bandwidth among the signal reception possible intervals.

[0119] Since the frequency band of the target signal B is 2.6 GHz to 3.1 GHz and the frequency band of the target signal C is 2.8 GHz to 3.4 GHz, even if the two target signals are merged, the frequency band is 2.6 GHz to 3.4 GHz, so it does not exceed the maximum reception bandwidth (0.8 GHz) of the receiver. Therefore, the reception plan generation unit (130) can merge the target signal B and the target signal C to generate a single merged frequency band of 2.6 GHz to 3.4 GHz.

[0120] Reference numeral 1302 is the intended reception bandwidth corresponding to the merged frequency band including the target signal B and the target signal C.

[0121] Reference numeral 1303 is the expected reception bandwidth corresponding to the target signal Da.

[0122] Reference numeral 1304 is the expected reception bandwidth corresponding to the target signal Db. The frequency band of the target signal Db is 7.053 to 7.846 GHz, but since the signal reception range is 2 GHz to 7.5 GHz, the range corresponding to the frequency band of the target signal within the signal reception range, which is 7.053 GHz to 7.5 GHz, can be the expected reception bandwidth.

[0123] Likewise, since the frequency band of the target signal Dc is 7.606 to 8.3 GHz and is outside the signal reception range, the reception plan generation unit (130) does not generate a reception planned bandwidth corresponding to the target signal Dc.

[0124] As described above, the reception plan generation unit (130) can generate a reception planned bandwidth after merging the target signal to be collected, but the present invention is not limited thereto and may merge multiple reception planned bandwidths or expand the generated reception planned bandwidth in a manner such as generating a reception planned bandwidth first and merging the target signal to be collected.

[0125] For example, the reception plan generation unit (130) checks whether there exists a reception planned bandwidth that completely includes the frequency band of the first target signal to be collected. If there exists a reception planned bandwidth that completely includes the frequency band of the first target signal to be collected, the reception plan generation unit (130) can register information about the first target signal to be collected in a signal reception plan by matching it with the reception planned bandwidth that completely includes the frequency band of the first target signal to be collected.

[0126] If there is no reception bandwidth that completely includes the frequency band of the first target signal to be collected, but there is a reception bandwidth that includes at least a portion of the frequency band of the first target signal to be collected, the reception plan generating unit (130) can expand the reception bandwidth that includes at least a portion of the frequency band of the first target signal to be collected so as to include the entire frequency band of the first target signal to be collected.

[0127] At this time, the intended reception bandwidth can be expanded so as not to include the second harmonic frequency of the minimum frequency of the corresponding reception bandwidth. In addition, as described above, it is obvious that it cannot be expanded to a size larger than the maximum reception bandwidth of the receiver.
