Design And Implementation Of Radar Data Comprehensive Processing System

With the rapid development of the national defense,more and more missile testing tasks are required,so does the higher measurement and control capability of the range.At present,the complexity of the measurement and control equipment system and the completeness of the data recording function have been greatly improved,but the quantity of subsequent processing data caused by this has been increased significantly,which makes the equipment personnel's data analysis ability and correlation analysis ability of the data,equipment and operation face serious tests,and there is a lot of valuable information in radar data which can't be extracted and applied.Therefore,it is urgently needed to develop a radar data comprehensive processing system that is mature,stable,fully functional and highly efficient.This paper takes a certain type target characteristic measurement radar in S band as the research object,and designs a data processing system for the radar.In order to solve the above problems,the following work has been completed:Based on the requirements of the target field test task and the characteristics of radar data synthesis processing theory and radar data composition,the theory of data processing,software design and target recognition are applied in this paper.The theoretical analysis,demand analysis,overall design,functional module design and the test task application analysis was carried out to design and verify a certain radar data integrated processing system.The main research of this paper is as follows:1.A preliminary study on the theory of radar data integrated processing is carried out.At first,the system structure of radar data processing system is analyzed from 3 aspects: centralized,separate and distributed architecture.Then combined with radar data processing the radar data processing system is analyzed from the aspects of data preprocessing,track data analysis,radar control process analysis and intermediate frequency data analysis,which lays a theoretical foundation for the subsequent system design and implementation.2.The composition and characteristics of the radar data are analyzed in this paper.Based on this,six functional design targets of the data processing system for the radar is proposed.The overall design of the software is carried out from 3 aspects: the architecture of the radar data processing system,the function module and the general control part.In particular,the overall design of functional modules such as data preprocessing,track data analysis,radar control analysis and intermediate frequency data processing provides support for the specific implementation of the radar data comprehensive processing system.3.Visual VC++ is used to build the software interface and realize the functions of data processing and analysis.3.According to the system and overall design requirements,a specific radar data integrated processing system is designed and implemented.Firstly,the mixed programming technology of VC++ and MATLAB is adopted.Combined with the modular design idea,the overall design of the system software is completed from the aspects of interface design and initialization module.Then the specific design of the data preprocessing,track data analysis,lightning control process analysis and intermediate frequency data processing are completed in turn combined with the overall design of the functional module.4.The radar data comprehensive processing system is verified and analyzed combined with conventional tasks and thematic applications.the basic process of data comprehensive processing in the whole process of task preparation,execution and completion is determined with the actuality of the shooting range test task.On the basis of these,the system is verified and analyzed in the routine task from the two aspects of task plan development and rapid task evaluation.Thematic application analysis was carried out from the aspects of loss of the female bomb,target separation,flight measurement,and active interference signal analysis.The results show that the designed radar data integrated processing system has achieved good application results in the test task and reached the design requirements.
