Design And Implementation Of A Scene Monitoring Security Radar Visualization Terminal Software

With the continuous improvement of FM linearity, now security radar mostly is linear frequency modulation system. The development of domestic radar technology is relatively later than foreign. As a result, the dominant radar systems in China are still pulse radar systems. The linear frequency modulation radar systems are widely used for measuring height. With the expansion of the further development of the domestic radar technology, as well as domestic market demand for security radar, China has developed a kind of security warning radar which is suitable for open environment, such as oil fields, border and etc. In recent years, the security radar working frequency band of China is also rising. When the operating frequency is high enough, the scene monitoring security radar can also be a foreign matter detection under certain circumstances. With the expansion of the radar’s functions, the scene surveillance radar can all-weather monitoring and early warning, that means it’s not affected by the environment and light, so it has been developing rapidly in the field of security. Variety radar products is more and more functions tend to improve, however radar cannot work without anyone man-machine communication terminal handling. Especially for large and complex radar system in terms of relatively good user-friendly control terminal is particularly important. Good performance, digital, humane control terminal will become an indispensably important part of the next generation radar systems.In this paper, the radar system and the main modules are introduced first. And then the radar control software is designed. The technical difficulties in the process of software design are discussed, and the method to solve those problems is given. This radar software includes two parts. One part is the visualization software which allows user simple controlling the radar. Another part is commissioning software which is used for setting, testing or repairing the radar, but the user of this part must have professional knowledge.The software including the main interface, the map display interface, data display interface and control interface is designed. and then detailed design work for the function of the program part is shown. For multi-tasking of the control computer, the threads are used to achieve the functions, such as the target data reading, displaying and uploading to the server. And then the pre-set software is designed, its funcation including acquisition data, storage data and digital signal processing.Finally, this paper gives the results for testing the two part of the software, and gives the analysis and summary for the results.
