In addition, in order to test the radar signal processing apparatus, scenario information is generated in the test equipment, target information is generated based on the scenario information, and the target information is generated as a radar signal, and the process of repeatedly transmitting the radar signal processing apparatus is performed. Should be. However, if the amount of data to be processed rapidly due to factors such as waveforms, target numbers, etc., there is a problem that the radar signal processing device cannot be smoothly tested by the load of the test equipment and the load of the network.

This may take a relatively long time to generate the scenario information and all the target information. In addition, since the generated information is collectively transmitted to the test environment simulator 120, there is a problem in that a lot of load is generated to transmit data in the initial stage of the test. In addition, since the scenario simulator 110 generates all the target information and transmits it to the test environment simulator 120, when the scenario is changed, it takes a relatively long time to reflect the changed scenario.

However, since the test environment simulator 120 generates the radar signal according to the reference signal of the waveform information of the radar signal processing device 150 and transmits the radar signal to the radar signal processing device 150 during the actual test operation, the network load is almost generated.

It will generate a radar signal. In this case, the test environment simulator 220 does not generate all the target information in a batch, but generates the target information in real time from the target information generator 222 and delivers the target information to the radar signal generator 224. The generation unit 224 generates the target information to be transmitted as a radar signal. That is, the test environment simulator 220 repeatedly performs the generation of the target information and the generation of the radar signal and transmits the generated radar signal to the radar signal processing device 150. When the radar signal processing apparatus 150 is tested in this manner, since the amount of data is relatively small when the number of targets is small, there is little load on the test environment simulator 220 and the network.

In this case, the target information generation unit 315 may generate and generate at least two or a plurality of target information within the test time and transmit the divided target information to the first storage unit 316. That is, instead of generating all the target information within the test time at once, the target information may be divided and generated according to the passage of time, and then sequentially transmitted to the first storage unit 316. When the scenario is modified, new target information can be quickly generated based on the modified scenario.

The first storage unit 316 may store various information input through the scenario input unit 312, scenario information generated by the scenario generator 314, and target information generated by the target information generator 315. In this case, the first storage unit 316 may store the target information generated by the target information generator 315 according to the generated order or the generated time. In this case, a plurality of target information generated by the target information generation unit 315 may form one unit information and may be stored in the first storage unit 316. In this case, the number of unit information may be less than the number of all target information.

The second distributor 323 may extract the target information stored in the second storage unit 322 after the target information is stored in at least two unit information in the second storage unit 322. At this time, after extracting one unit information from the test environment simulator 320, at least one unit information should remain in the second storage unit 322. This is because the transmission of the target information in the scenario simulator 310 may be delayed according to the target number and period. That is, the generation of the target information in the scenario simulator 310 may be delayed according to the number of targets and the period, and thus the transmission of the target information to the test environment simulator 320 may be delayed. Accordingly, even when transmission of the target information is delayed in the scenario simulator 310, the radar signal may be smoothly generated using the target information temporarily stored in the second storage unit 322.

When the scenario information is generated, the target information generation unit 315 may generate the target information based on the scenario information. The target information generator 315 may generate some target information of all the target information without generating all the target information within the test time. In this case, the target information generator 315 may generate at least two or more pieces of target information and transmit the generated target information to the first storage unit 316. The first storage unit 316 may store two or more pieces of target information generated by the target information generator 315 in the form of unit information.

The environment may be transmitted to the simulator 320.

Here, it was described that the target information stored in the first storage unit 316 is extracted for each unit information through the first distribution unit 317 and transmitted to the test environment simulator 320. However, as shown in FIG. 5, when the target information is generated, unit information including two or more pieces of target information may be generated and transmitted directly to the test environment simulator 320 through the first communication unit 318. In this case, the generated target information may be stored in the first storage unit 316.

The test environment simulator 320 may receive target information transmitted from the scenario simulator 310 through the second communication unit 326 and store it in the second storage unit 322. In this case, the target information may be stored in the second storage unit 322 in the received order, and may be stored in the form of unit information.

Thereafter, the second distributor 323 may extract the target information stored in the second storage unit 322 and transmit the extracted target information to the radar signal generator 324. In this case, the second distribution unit 323 may extract the target information stored in the second storage unit 322 after the target information is stored in the form of at least two unit information. The second distributor 323 may extract the target information in the order in which the target information is stored, that is, in the order transmitted from the scenario simulator 310, and may extract the target information for each unit information. After extracting one unit information stored in the second storage unit 322 through the second distribution unit 323, at least one or more unit information should remain in the second storage unit 322.

When the target information is extracted for each unit of information in the second distribution unit 323, the target information may be delivered to the radar signal generator 324 in a plurality of target information constituting the unit information in the generated order. In this case, the second distributor 323 may transmit the target information to the radar signal generator 324 in the order of generation. After the radar signal generator 324 generates the target signal as a radar signal, the radar signal generated through the second communication unit 326 may be transmitted to the radar signal processing device 150.

The radar signal processing apparatus 150 may process the radar signal transmitted from the test environment simulator 320 and then transmit the processing result to the test data analyzer 330.

The test data analyzer 330 may receive test data from the scenario simulator 310, the test environment simulator 320, and the radar signal processing device 150 to analyze the performance of the radar signal processing device 150. . In addition, the analysis result may be output to the display unit 140 so that an operator may check the analysis result.

When the radar signal processing apparatus is tested in this manner, since the radar signal is generated using only a part of the target information stored in the second storage unit 322, the generation and transmission of the target information in the scenario simulator 310 is delayed. Even if the radar signal can be generated continuously. In addition, since most information, including target information, is divided and generated and transmitted, it is possible to suppress the occurrence of load on each of the components constituting the test equipment, and to suppress the load on the network. In particular, the creation and transmission of target information can be segmented, reducing the waiting time for testing.

In addition, the scenario simulator 310 may generate target information by dividing the target information based on the scenario information, and may make the divided target information into a packet form and transmit it to the test environment simulator 320. Accordingly, while testing the radar signal processing apparatus 150 using the target information generated based on the scenario information before the modification, new target information is generated based on the modified scenario information to test the radar signal processing apparatus 150. Can be reflected in real time.

Hereinafter, a test example for verifying a test method of a radar signal processing apparatus according to an exemplary embodiment of the present invention will be described. This test example looks at the waiting time for the test.

The radar signal processing apparatus was tested using the test equipment shown in FIGS. 1, 2 and 3. Here, the test performed using the test equipment shown in FIG. 1 is Comparative Example 1, and the test performed using the test equipment shown in FIG. 2 is the comparative test example 2, which is performed using the test equipment shown in FIG. Yes.

The test was performed using test equipment having the specifications listed in Table 1 below.

division Specification CPU Intel Core i7-8700 RAM 16 GB VGA Feforce GTX 1060 Storage SSD 512 GB IF 1 Gbit Ethernet

The test was carried out as follows.

The control command repetitively transmitted the control data of about 100 bytes in a period of 20 ms.

Target information was generated by calculating target information using a radar equation according to a reference signal or a synchronization signal.

Target extraction aligns all target information and extracts target information by synchronization signal.

Radar signal generation generates a radar signal using beam information and target information.

As a result of the test, Comparative Example 1 generates 10 minutes of scenario information based on 40 bytes of target information, 3000 targets, and 1 dB of reference signal to generate and deliver all target information corresponding to the scenario. Needed. This is because the scenario simulator generates all the target information and sends it to the test environment simulator, so it takes a relatively long time to start the test.

In Comparative Example 2, when scenario information is generated in the scenario simulator, the test environment simulator performs target information, and thus no waiting time occurs.

On the other hand, in the case of the embodiment, the scenario simulator divides and generates some of all the target information, which takes about 10 seconds and takes about 9 seconds of waiting time. In the embodiment, the waiting time is shorter than that of Comparative Example 1 and longer than that of Comparative Example 2, but is almost negligible. Therefore, when the scenario is modified during the test, the test can be performed by quickly reflecting the modified scenario.

Accordingly, one of ordinary skill in the art may variously modify and modify the present invention without departing from the technical spirit of the following claims.
