Design And Realization Of A Data Acquisition Applied In The Radar

With the development of electronic shooting range, the tasks of shooting range is been changing gradually from the traditional accuracy test to electronic countermeasures.In the test, more data with different type need to be acquired. One radar range is an important set of experimentation equipment of the shooting range. The existent data acquisition system can no longer continue to be used as the result of taking the system, backward technology, the aging components and other reasons. The thesis introduced the detail of designing new data acquisition system, discussed the form of data output and electric property, developed the data collection terminal based on SCM Technology, and developed a data collection application software.The article has proposed the scheme, technical indicators and system components of a radar data acquisition system. The article also analyzed and explained the function and key technology of the system. With the novel design of separating radar data transform and acquisition, the program solved the original system's problem of being too complex. The system includes two parts: the radar data interface terminal and the radar data acquisition computer. The radar data interface terminal is used for transforming radar interface data to RS232 standard series data and transforming RS232 standard series interface guide data to data which adapt to the radar. The radar data acquisition computer is used for acquiring transformed radar data from radar data interface terminal.After finishing the update of the radar computer system, the performance unsteadiness of original system has been fixed. It has preferably achieved functions like data input, time marking, pretreatment, storing, and transmit when running. So that the reliability and stability of the whole system has been enhanced. The complete set of the system has been well designed, technically advanced, functionally complete, and running stabile. It has done a great contribution in several examinations, and has great military and economic benefits.The system has great practicability and expansibility, so that can accomplish the usage in shooting range...
