Description

TECHNICAL FIELD

[0001] The present invention relates to a radar sensor device, a radar system, a setting information adjustment device, a learning data collection system, a setting information adjustment method, a learning data collection method, and a program for supporting a user using a radar.

BACKGROUND ART

[0002] The main purpose of use of marine radars is collision prevention, and it is necessary to grasp the trends of other ships and obstacles such as navigation buoys and breakwaters near the own ship. A radar emits radio waves, subjects the reflected signals thereof to signal processing to generate radar image data, and then performs coordinate transformation to visualize the data. Unwanted reflections from waves and rain clouds, sensitivity reduction due to fog and haze, interference from radars mounted on other ships, and false images caused by multipath from strongly reflective targets are also visualized, which may make it difficult to distinguish the targets that are originally intended to be viewed. For this reason, marine radars are equipped with image adjustment functions such as a sea surface reflection removal function, a rain and snow reflection removal function, an interference removal function, a temporal correlation function, and an image enlargement function, and can be used by appropriately activating these functions to adjust the image for easier target viewing. Non-Patent Document 1 is known as a document containing descriptions of such radars. In addition, Patent Documents 1 to 3 and the like are known as techniques for realizing the aforementioned functions.

NON-PATENT DOCUMENT 1

[0005] Marine radar often encounters problems such as difficulty distinguishing between waves and targets, targets becoming invisible within rain clouds, and multipath interference from strong radio wave reflectors obscuring desired objects. Therefore, while several radar image adjustment functions are available to suit different sea conditions, incorrect adjustments can result in objects disappearing or becoming obscured by noise. Radar instruction manuals describe the usage and effects of these functions, but they cannot fully explain the optimal image adjustment method for all sea conditions, including the combination of functions and subtle signal strengths. Furthermore, each user has different preferences regarding the targets they want to see and the desired image. For example, some may want to display only nearby ships, others may want to display rain clouds alongside ships, and still others may want to change how land is viewed.

[0006] If users are unable to make the necessary adjustments, radar manufacturers repeatedly have users try out settings that they believe will be effective, based on photographs or screenshots of the radar screen they are viewing and the settings they have obtained, until the radar image is satisfactory to the user. However, this method cannot cover all the settings. Furthermore, it is difficult to give accurate adjustment instructions unless an experienced person who can anticipate the user's usage is present. It would be ideal to go to the site and make adjustments in front of the user, but the number of experienced people is limited, and it is difficult to reproduce situations such as boats not being able to go out due to the ever-changing sea conditions, or targets disappearing in the rain, making it difficult to make optimal adjustments in a short period of time and satisfy the user. For these reasons, it is difficult to give instructions that will satisfy the user for each day's changing sea conditions.

[0007] This invention was made in view of these circumstances and aims to provide a technology that can support users of radar. [Means for solving the problem]

[0008] The radar sensor device of the present invention comprises a radar receiving unit, a device setting information acquisition unit, a device processing unit, and a data output unit. The radar receiving unit receives reflected waves of transmitted waves and acquires intermediate frequency digital data, which is the digital data of the intermediate frequency signal. The device setting information acquisition unit acquires device setting information, which is the setting information for processing to be performed on the intermediate frequency digital data. The device processing unit outputs processed data, which is data processed according to the device setting information on the intermediate frequency digital data. The data output unit outputs radar data that associates the intermediate frequency digital data, the processed data, and the device setting information. [Effects of the Invention]

[0009] According to the radar sensor device of the present invention, radar data can be acquired by associating intermediate frequency digital data, data processed by the actual device, and actual device setting information. Therefore, it is possible to accurately confirm how the user used the radar in the field. Thus, it is possible to support users who use radar. [Brief explanation of the drawing]

[Figure 7] A diagram illustrating an example of a computer's functional configuration. [Modes for carrying out the invention]

[0011] The embodiments of the present invention will be described in detail below. Components having the same function will be given the same number, and redundant explanations will be omitted. [Examples]

[0012] Figure 1 shows an example of the functional configuration of the radar sensor device of Embodiment 1, and Figure 2 shows an example of the functional configuration of the radar system. Figure 3 shows an example of the processing flow in the setting information adjustment device of Embodiment 1. The radar system 10 consists of a radar 200 including the radar sensor device 100 and a setting information adjustment device 300. The radar sensor device 100 includes at least a radar receiving unit 150, a real-device setting information acquisition unit 160, a real-device processing unit 170, and a data output unit 180. More specifically, as shown in Figure 1, the radar sensor device 100 may include a transmitting circuit 110, an antenna unit 120, a receiving circuit 130, an intermediate frequency conversion unit 140, an A / D conversion unit 145, a radar receiving unit 150, a real-device setting information acquisition unit 160, a real-device processing unit 170, a data output unit 180, and a recording unit 190.

[0013] The transmitting circuit 110 generates a transmission signal to be transmitted from the antenna unit 120. The antenna unit 120 transmits a transmission wave corresponding to the transmission signal and receives the reflected wave. The receiving circuit 130 outputs the received reflected wave as a reflected signal. The intermediate frequency conversion unit 140 converts the reflected signal, which is RF (Radio Frequency), into an analog intermediate frequency signal, which is IF (Intermediate Frequency). The A / D conversion unit 145 converts the intermediate frequency signal, which is an analog signal, into intermediate frequency digital data. The radar receiving unit 150 is a combination of the part of the antenna unit 120 related to receiving the reflected wave, the receiving circuit 130, the intermediate frequency conversion unit 140, and the A / D conversion unit 145. The radar receiving unit 150 receives the reflected wave of the transmission wave and acquires intermediate frequency digital data, which is the digital data of the intermediate frequency signal.

[0014] The actual-device setting information acquisition unit 160 acquires actual-device setting information, which is setting information for processing performed on intermediate frequency digital data. The setting information is information for performing settings such as sea surface reflection removal, rain and snow reflection removal, and interference removal, and may be acquired from the operation unit 250 of the radar 200. The actual-device processing unit 170 outputs actual-device processed data, which is data obtained by performing processing on the intermediate frequency digital data in accordance with the actual-device setting information. Both the "intermediate frequency digital data" and the "actual-device processed data" are so-called sweep data, and may be data obtained by collecting a predetermined number of pieces of sweep data. For example, the data may be data obtained by collecting sweep data at every 0.25 degrees for one rotation (360 degrees), or data obtained by collecting sweep data for a plurality of rotations.

[0015] The recording unit 190 records radar data in which the intermediate frequency digital data, the actual-device processed data, and the actual-device setting information are associated with each other. The data output unit 180 outputs radar data in which the intermediate frequency digital data, the actual-device processed data, and the actual-device setting information are associated with each other. The recording unit 190 may further record the radar data in association with information on the azimuth and characteristics of the transmission wave and the position information of the radar sensor device 100. In this case, the data output unit 180 also associates the radar data with the information on the azimuth and characteristics of the transmission wave and the position information of the radar sensor device 100. The "characteristics" refer to the output of the transmission wave, the pulse width, the repetition period, the resolution of distance and azimuth, information related to the antenna, and the like. The "azimuth" is the azimuth at which the transmission wave for each piece of sweep data is transmitted. The "position information" may be latitude and longitude. The recording unit 190 may also record sea state information associated with the radar data. The "sea state condition" refers to weather, wind direction, wind speed, wave height, tidal current, and the like. When the sea state information is recorded, by using it as input information for an artificial intelligence-based learning data collection system, it is expected that efficient learning can be achieved by focusing on similar radar data from the same sea state information among the accumulated radar data. Note that information such as coordinate conversion, time correlation, and image enlargement to be processed by an actual-device image processing unit 275, which will be described later, may be further added to the radar data.

[0016] The radar 200 includes a radar sensor device 100, and further comprises a radar data transmission unit 210, an actual-device image processing unit 275, an actual-device display unit 280, and an operation unit 250. The radar data transmission unit 210 transmits radar data to the setting information adjustment device 300. Note that the radar data transmission unit 210 may be arranged inside the radar sensor device 100. The actual-device image processing unit 275, the actual-device display unit 280, and the operation unit 250 are configurations that are also provided in general radars. The actual-device image processing unit 275 has functions such as a coordinate conversion function, a time correlation function, and an image enlargement function for actual-device processed data. The actual-device display unit 280 displays the output of the actual-device image processing unit 275. The operation unit 250 is provided for inputting setting information (information related to the sea surface reflection removal function, rain and snow reflection removal function, and interference removal function) and image processing information (information related to the coordinate conversion function, time correlation function, image enlargement function, etc.). The input of the setting information and image processing information to the operation unit 250 may be performed manually by a user, or the adjusted setting information output from the adjusted setting information transmission unit 390 of the setting information adjustment device 300 described later may be input.

[0017] The setting information adjustment device 300 includes a radar data acquisition unit 310, an adjusted setting information acquisition unit 360, an adjustment processing unit 370, an adjusted image processing unit 375, and an adjustment display unit 380. The setting information adjustment device 300 may also comprise an adjusted setting information transmission unit 390. The setting information adjustment device 300 is arranged in a support office of an enterprise that manufactures and sells the radar 200, and is premised on use during support by a skilled person.

[0018] The radar data acquisition unit 310 acquires radar data (S310), which is data that associates intermediate frequency digital data, which is digital data of the intermediate frequency signal obtained from the received reflected wave, actual device setting information, which is setting information for processing performed on the intermediate frequency digital data, and actual device processed data, which is the intermediate frequency digital data processed by the actual device setting information. The radar data may also include information on the direction and characteristics of the transmitted wave, the position information of the radar sensor device 100, etc. The radar data acquisition unit 310 may acquire radar data by receiving it from the radar data transmission unit 210 via a network, or it may acquire radar data via a recording medium.

[0019] The adjustment setting information acquisition unit 360 acquires adjustment setting information, which is setting information for processing performed on intermediate frequency digital data (S360). The adjustment setting information can be set by an expert or an artificial intelligence (model) that has learned the skills of an expert. At the time of filing this application, there is no artificial intelligence that can replace an expert. At the time of filing this application, the adjustment setting information must be entered by an expert. However, if experts are to handle this, there are limitations in the number of people and working hours, making it difficult to support users using radar 24 hours a day. On the other hand, considering the operation of ships, 24-hour support is required. Embodiment 2, which will be described later, will describe the collection of learning data for training artificial intelligence to learn the skills of an expert.

[0020] If the radar data acquisition unit 310 can receive radar data from the radar data transmission unit 210 via the network, an expert can check the status of the radar 200 in real time. If the radar data acquisition unit 310 acquires radar data via a recording medium, real-time support by an expert is not possible, but it can be used to explain the proper usage to the user.

[0021] The adjustment processing unit 370 processes the intermediate frequency digital data of the radar data according to the adjustment setting information and outputs the adjusted data (S370). The adjustment image processing unit 375 outputs a radar image on which coordinate transformation, time correlation, image magnification, etc. have been performed on the actual processed data or the adjusted data (S375). If the radar data also has information such as coordinate transformation, time correlation, and image magnification added to it, the adjustment image processing unit 375 may be made to output a radar image on which processing has been performed based on the information added to the radar data. In other words, the adjustment image processing unit 375 outputs a radar screen based on the actual processed data of the radar data or a radar screen based on the adjusted data. The adjustment display unit 380 displays the radar image output by the adjustment image processing unit 375 (S380). The adjustment display unit 380 may display only one of the radar screens, the one based on the actual processed data of the radar data or the one based on the adjusted data, or it may display them side by side. If the radar data has sweep data for one rotation, the displayed radar screen may be a still image. If the radar data includes sweep data that combines multiple rotations, the displayed radar screen may be a video or a still image at a timing specified by the operator (expert).

[0022] An experienced operator can verify the appropriateness of the adjustment setting information based on the display on the adjustment display unit 380. If the adjustment setting information is not appropriate, the process can be repeated (S301). If communication is possible, the experienced operator can convey the appropriate adjustment setting information to the user. Furthermore, if the setting information adjustment device 300 also has an adjustment setting information transmission unit 390, the experienced operator can transmit the adjustment setting information from the adjustment setting information transmission unit 390 to the operation unit 250 of the radar 200 (S390). When the actual machine processing unit 170 receives the adjustment setting information, it can output the data processed according to the adjustment setting information on the intermediate frequency digital data as actual machine processed data.

[0023] The radar sensor device 100 can acquire radar data that associates intermediate frequency digital data, data processed by the actual device, and actual device setting information. Therefore, it is possible to accurately confirm how the user used the radar in the field. Thus, it is possible to support users who use the radar. Furthermore, by using the setting information adjustment device 300, it is also possible to adjust the setting information and confirm its appropriateness, thereby providing more appropriate support to users who use the radar. [Examples]

[0024] In the description of the adjustment setting information acquisition unit 360 in Example 1, the usefulness of artificial intelligence (model) that has learned the skills of an expert was explained. In Example 2, the collection of learning data for training artificial intelligence to learn the skills of an expert is described. Figure 4 shows an example of the functional configuration of the radar sensor device in Example 2, and Figure 5 shows an example of the functional configuration of the learning data collection system. Figure 6 shows an example of the processing flow in the setting information adjustment device in Example 2. The learning data collection system 20 consists of a radar 201 including the radar sensor device 101 and a setting information adjustment device 301.

[0025] The input to the artificial intelligence is intermediate frequency digital data and the purpose of processing according to the adjustment setting information. The "purpose" refers to whether to prioritize sea surface reflection removal, rain / snow reflection removal, or interference removal, or whether to display only surrounding ships, or to display rain clouds together with ships, etc. If a list of purposes is to be created, one can select from the list. The output from the artificial intelligence is the adjustment setting information. Therefore, in Example 2, a set of training data for the artificial intelligence is collected, with intermediate frequency digital data and the purpose as input data and adjustment setting information as output data.

[0026] The radar sensor device 101 includes at least a radar receiving unit 150 and a data output unit 181. More specifically, as shown in Figure 4, the radar sensor device 101 may include a transmitting circuit 110, an antenna unit 120, a receiving circuit 130, an intermediate frequency conversion unit 140, an A / D conversion unit 145, a real-device setting information acquisition unit 160, a real-device processing unit 170, a data output unit 181, and a recording unit 191. The transmitting circuit 110, antenna unit 120, receiving circuit 130, intermediate frequency conversion unit 140, A / D conversion unit 145, radar receiving unit 150, real-device setting information acquisition unit 160, and real-device processing unit 170 are the same as in Embodiment 1. The recording unit 191 records the intermediate frequency digital data output by the radar receiving unit 150. The data output unit 181 then outputs the intermediate frequency digital data output by the radar receiving unit 150. The data output unit 181 has a communication function and may transmit intermediate frequency digital data to the setting information adjustment device 301.

[0027] Radar 201 comprises a radar sensor device 101, a real-time image processing unit 275, a real-time display unit 280, and an operation unit 250. The real-time image processing unit 275, the real-time display unit 280, and the operation unit 250 are the same as in Embodiment 1. Note that the radar sensor device 101 and radar 201 may be exactly the same as the radar sensor device 100 and radar 200. In that case, the data output unit 180 will output radar data, but this is not a problem as it includes intermediate frequency digital data.

[0028] The setting information adjustment device 301 comprises a recording unit 391, an adjustment setting information / purpose acquisition unit 361, an adjustment processing unit 370, an adjustment video processing unit 375, and an adjustment display unit 380. The adjustment processing unit 370, the adjustment video processing unit 375, and the adjustment display unit 380 have the same functions as in Embodiment 1. However, if data already processed by the actual machine is not recorded in the recording unit 391, processing of the data already processed by the actual machine will not be performed.

[0029] The recording unit 391 first acquires and records intermediate frequency digital data (S391). The adjustment setting information / purpose acquisition unit 361 acquires adjustment setting information, which is setting information for processing to be performed on the intermediate frequency digital data, and the purpose of processing according to said adjustment setting information (S361). The adjustment setting information and purpose can be input by an experienced operator of the setting information adjustment device 301. The adjustment processing unit 370 performs processing on the intermediate frequency digital data according to the adjustment setting information and outputs the adjusted data (S370). The adjusted image processing unit 375 outputs a radar image on which coordinate transformation function, time correlation function, image magnification function, etc. have been performed on the adjusted data (S375). In other words, the adjusted image processing unit 375 outputs a radar screen based on the adjusted data. The adjustment display unit 380 displays the radar image output by the adjusted image processing unit 375 (S380).

[0030] An experienced user can verify the appropriateness of the adjustment setting information based on the display on the adjustment display unit 380. If the adjustment setting information is not appropriate, the process can be repeated (S302). If the experienced user determines that the adjustment setting information is appropriate, the recording unit 391 records a set of learning data in which the intermediate frequency digital data and the target are input data and the adjustment setting information is output data (S392).

[0031] Furthermore, if the adjustment setting information acquisition unit 360 in the setting information adjustment device 300 is changed to an adjustment setting information / purpose acquisition unit 361 and a recording unit 391 is provided, the radar system 10 can also function as a learning data collection system 20.

[0032] According to the learning data collection system 20, intermediate frequency digital data is collected from the radar 201 used by the user, and the setting information adjustment device 301 can be easily operated by an expert. This allows for the collection of sets of learning data for artificial intelligence, with intermediate frequency digital data and the target as input data, and adjustment setting information as output data.

A processor includes transistors and other circuits and is considered a circuitry or processing circuitry. A processor may be a programmed processor that executes a program stored in memory.

[0034] In this specification, circuitry, unit, and means are hardware programmed to perform or execute the functions described herein. Such hardware may be any hardware disclosed herein, or any hardware known to be programmed to perform or execute the functions described herein.

[0035] If the hardware is a processor that is considered to be a type of circuitry, then the circuitry, means, or unit is a combination of hardware and software used to constitute the hardware and / or processor.

[0036] The various processes described above can be carried out by loading a program that executes each step of the above method into the recording unit 2020 of the computer 2000 shown in Figure 7, and then causing the control unit 2010, input unit 2030, output unit 2040, display unit 2050, etc. to operate.

[0037] The program describing this process can be recorded on a computer-readable recording medium. Any computer-readable recording medium can be used, such as a magnetic recording device, optical disc, magneto-optical recording medium, or semiconductor memory.

Alternatively, the program may be stored in the storage device of a server computer and distributed by transferring the program from the server computer to other computers via a network.

[0039] A computer executing such a program may, for example, first store the program, either recorded on a portable storage medium or transferred from a server computer, in its own storage device. Then, when processing is to be executed, the computer reads the program stored in its storage device and executes the processing according to the read program. Alternatively, the computer may directly read the program from the portable storage medium and execute the processing according to that program, or it may sequentially execute the processing according to the received program each time a program is transferred to it from a server computer. Furthermore, the processing may be executed using a so-called ASP (Application Service Provider) type service, where the processing function is realized only by issuing execution instructions and obtaining results, without transferring the program from the server computer to this computer. Moreover, the processing may be executed using a so-called SaaS (Software as a Service) type service, where a part of the server computer is made available to the user along with the program. In this form, the program includes information used for processing by an electronic computer that is equivalent to a program (data that is not a direct instruction to the computer but has the property of defining the computer's processing).

[0040] Furthermore, in this configuration, the device is configured by executing a predetermined program on a computer, but at least a part of these processes may be implemented in hardware. [Explanation of Symbols]
