Radar Cross Section(RCS)measurement is an important method to study the electromagnetic scattering characteristics of radar targets and target identification.In order to deeply study the electromagnetic scattering characteristics of plasma-coated targets,a set of high-precision RCS imaging measurement system has been built by the National Major Scientific Research Instrument Project.This high-precision RCS imaging measurement system measures a closed cavity environment with high temperature and vacuum,which makes it impossible for people to enter the experimental environment to operate during the experiment.The above problems can be solved by remotely controlling the entire experimental process through a computer.The main content of this paper is the development of measurement and control software for the RCS imaging measurement system based on the RCS imaging measurement system.Aiming at the complex measurement environment in the RCS measurement and the need to process the measurement data in real time and display the data processing results,a set of C# The measurement and control software of the RCS imaging measurement system mixed with MATLAB is tested,and the measurement and control software is tested in combination with the required functions of the RCS imaging measurement system.This article mainly carried out the following work:1.I will study the relationship between the basic theoretical knowledge of RCS measurement and the function of each hardware device of the RCS image measurement system.First,the definition of radar scattering cross section is derived from various angles.Next,we will introduce the far field condition measurement RCS and relative calibration method in detail according to the actual development requirements of the project.Next,I will briefly introduce the hardware platform of the entire system.2.Based on the RCS imaging measurement system,the design of the measurement and control software of the RCS imaging measurement system is completed.First,the timing of the system is designed.Secondly,it analyzes the functions required by the measurement and control software,and analyzes the development of the measurement and control software from the perspective of technical feasibility through the difficulties of software development.Finally,according to the concept of modular design,each module is designed separately.And add some non-functional designs to the measurement and control software from the point of view of software development.3.Various functions of the measurement and control software are realized.Firstly,the selection of development tools of measurement and control software is analyzed,and the necessary related technologies for development are studied.Then the logic structure of the measurement and control software is analyzed in detail,researched the mainstream C/S architecture and B/S architecture,the interaction protocol between the integrated control computer and the higher computer is designed,and finally the mixed programming in C #and MATLAB is completed.The method to develop the measurement and control software and the realization process of each function is introduced according to the module.4.Black-box testing of the functions of each module of the measurement and control software and testing of software reliability.Firstly,the commonly used software testing methods are studied.Then,the functions that can be realized by each module after the test are given,and then the reliability of the software is verified,and finally the test of the RCS imaging measurement system measurement and control software is completed.By analyzing the test results,it is verified that the functions of the measurement and control software meet the system measurement requirements.The measurement and control software of the RCS imaging measurement system designed in this paper can realize the remote control of the measurement system through the host computer and the high-precision RCS automatic measurement of targets in extreme measurement environments.The development of measurement and control software meets the needs of high-precision RCS measurement of targets for major national scientific research instrument projects.
