Hierarchical Adaptive Monitoring Technology Of Radar Information Processing Platform Based On Soft Bus

With the continuous innovation and development of radar technology the future radar will develop toward distributed architecture,intelligent processing,optoelectronic systems,multi-sensors and joint detection of land,sea,air and space.The development trend of radar technology puts forward higher requirements for integrated information processing systems,requiring integrated processing systems to meet the needs of multi-functional,reconfigurable,multi-channel,high-bandwidth and fine-grained processing,while ensuring long-term radar missions.Continuous and stable work.In order to meet the high bandwidth,strong real-time and high reliability of the radar information processing system,timely and complete monitoring of the working state of the radar information processing system is necessary.Because the radar information processing system has the characteristics of large-scale real-time running tasks,a large number of parallel working nodes,and a wide variety of devices participating in the work,it brings certain difficulties to the design of the radar information processing platform monitoring system.Based on the development and research work of the self-controllable high-performance DSP "Hua Rui 2" processing platform,this thesis realizes the real-time real-time operation of the radar signal processing platform by using the hierarchical adaptive monitoring technology based on the open soft bus.Monitoring provides strong support for information processing system fault reconfiguration,task scheduling and resource allocation.At present,this thesis has realized the design of hierarchical adaptive monitoring system based on soft bus architecture,and completed the monitoring function on the localized Huarui platform and X86 platform.At the same time,the monitoring management system has the functions of resource deployment and fault reconstruction.Compared with the traditional monitoring system,the radar signal processing platform system based on soft bus has the advantages of fine particle size,easy tailoring,cross-platform operation,stronger robustness,and the ability of fault reconfiguration and resource deployment.The experimental results show that the monitoring system can effectively provide strong support for the stable operation of radar signal processing platform.
