The Design And Realization Of Radar Signal Processing Components's Automated Test System

The radar signal processing system is the core of the radar system.It consists of multiple components.The component is a signal processing module that realizes specific functions.The success of radar operation is closely related to the quality of components.Therefore,component testing is very important.The introduction of automated test technology can achieve the test quality while reducing the test time,but due to the special test process of the radar signal processing component,the automated test tools on the market can not meet the test requirements.Therefore,this thesis designs and implements an automated test system for radar signal processing components,automatically generates test cases and test functions,automates real-time testing and generates test reports.This thesis mainly includes:1.By analyzing the versatility and particularity of radar signal processing component testing,the idea of building component interface model and keyword function library is proposed.The test model generation,real-time test function generation,and component interface parameter information and special attributes required in the result comparison analysis process are summarized to design a general model structure.At the same time,the keyword function library is designed to handle the special attribute requirements of the component parameters.2.Based on the current situation of software testing,a data-driven testing framework based on component interface model is designed.The framework not only realizes the separation of test cases and test scripts,but also automatically generates test cases and test functions based on the component interface model.3.Based on the test framework design automated test system,the test system is divided into component interface model management,test case generation,automated real-time test,test report generation and keyword function library module,and the detailed design and implementation of these five models.4.Design the test case to verify the various functional modules of the system,and use an actual component as an example to apply the system to complete the automated test process,and finally analyze the system execution efficiency.According to the actual test results,the automatic test system of the radar signal processing component shortens the test time compared with the manual test,especially when the number of components increases and the number of test cases increases,the test efficiency is particularly prominent.
