Description

Technical Field

[0001] The present invention relates to the technical field of software testing, and in particular to a testing method and platform for a target capture square wave signal frequency calculation module. Background Art

[0002] In the contemporary advanced electronic system architecture, the seeker undoubtedly occupies a core position. As a key component for target detection and tracking, its performance is directly related to the performance of the entire system. During the mission of the seeker, once the target is successfully locked, it will output a very characteristic target acquisition signal in the form of a square wave. It is worth noting that the frequency of this signal is not constant, but is closely related to the scanning and processing cycle of the seeker itself, and continues to fluctuate within a given frequency range. This dynamic change characteristic precisely reflects the working strategy adopted by the seeker in a complex and changing environment to achieve continuous and accurate monitoring and stable tracking of the target. The software under test plays an extremely important role in the operation of the entire electronic system. It mainly uses the interrupt mechanism to accurately collect the time difference between the rising edge and the falling edge of the target capture square wave signal, and then obtains the frequency value of the signal through complex and accurate algorithm calculations. Based on this frequency calculation result, the software will further perform key operations, that is, according to the frequency judgment result, flexibly set or clear the target capture flag, so as to accurately feedback the real-time status information of the target capture to other related modules in the system. In the process of dynamic testing of the software, in order to ensure the comprehensiveness and accuracy of the test results, it is necessary to highly simulate the signal input conditions in real scenarios, aiming to comprehensively test the reliability of the frequency calculation function and the stability of the performance of the software when it continuously receives the target capture signal whose frequency changes randomly within a specific range. However, looking back at the test methods used in the past, many disadvantages have gradually emerged. In traditional practices, it is more common to use a signal generator to output a set of square wave signals with a fixed period for testing. Although this method is relatively simple in operation, due to the significant difference in frequency characteristics between the square wave signal with a fixed period and the actual target capture signal, it is impossible to truly reproduce the dynamic change process of the signal in the actual working scenario, resulting in the test process being unable to fully cover the functional performance of the software in a complex signal environment, and ultimately making it difficult for the test results to fully reflect the true performance of the software. Another test strategy that was often used in the past is to send a square wave signal that changes according to a specific rule. However, in actual operation, this method encountered serious technical difficulties. Since it is difficult to accurately control the frequency value of the square wave signal in each software processing cycle, it is impossible to obtain effective theoretical expected results conveniently and accurately during the test process. This makes it difficult to conduct a scientific and reasonable comparison and analysis between the actual measured results and the expected results in the subsequent data comparison link, which greatly increases the difficulty of the test work and makes it difficult for the test work to achieve the expected results and goals. In summary, in order to significantly improve the accuracy and integrity of software testing, it is urgent to develop a target acquisition square wave signal generation scheme that can flexibly achieve single-cycle adjustable frequency. This scheme aims to simulate the target acquisition signal actually output by the seeker with high fidelity, thereby overcoming this key technical problem in the field of electronic system testing and promoting the level of electronic system performance testing to a new level.
