With the continuous advancement of integrated circuit manufacturing process,the system on chip(So C)technique has gradually attracted more and more attention.With respect to the engineering of radar signal processing,the development of So C technique has brought both new opportunities and challenges.In this thesis,the design and development of the missile-based radar signal processor system based on multi-processor So C(MPSo C)is the main research content.Combined with the performance advantages of Xilinx's second-generation all programmable Zynq Ultra Scale + MPSo C series chips,a single-chip architecture of the radar signal processor hardware platform is designed,which ensures that the signal processor meets the design requirements of miniaturization,low power consumption and high reliability.In addition,the complex MPSo C signal processing can be designed under various working modes and with different transmitting waveform parameters.Furthermore,the whole system comprehensive testing and verification as well as performance analysis are completed.The main content of this thesis can be summarized as follows.Firstly,the internal resources of Zynq Ultra Scale + MPSo C series chips are introduced in detail.By comparing with the current mainstream hardware platform architecture,the ZU9 EG chip is selected as the core processor according to the processing performance requirements of the system.Therefore,a single-chip hardware architecture is designed with the chip.The designed hardware platform has the characteristics of rich on-chip resources,strong scalability,high-speed interfaces,high stability,low system power consumption,and large storage to meet the processing requirements of large data volume and complex algorithms.Secondly,the overall design of the radar signal processor system and the algorithm implementation process are presented in detail.In order to meet the detection task in the complex battlefield environment,the radar signal processor has multiple working modes and transmitting waveforms,resulting in different processing flow in each working mode.In the practical working process,it is necessary to flexibly configure the working state of the system and parameter.Since the system is designed based on MPSo C,to achieve the best performance of the main controller,it is necessary to carry out reasonable software and hardware division of each module of the system and select appropriate development environment and design flow.At the same time,in order to ensure stable and high-speed communication between the interior of the radar signal processor and other sub-systems,the system adopts multiple communication protocols according to the characteristics of different processing stages during design,making full use of the resource advantages of the hardware platform to improve the system processing speed.The signal processor system involves a variety of processing algorithms.However,the emphasis is put on the hardware implementation of the algorithm.Besides,only the algorithm implemented by the programmable logic part is introduced.Finally,according to the application requirement,the radar signal processor has been thoroughly tested by constructing a semi-physical simulation test system.The test verification scheme of the system is mainly composed of the following two aspects.First,to ensure that the processing performance of the algorithm meets the design requirements,the signal processing algorithm is verified by hardware functioning and the comparison with MATLAB theoretical simulation results.Second,the signal processing hardware implementation results of the whole process of the machine has been verified.The PC software,echo simulator and simulation parameters involved in the verification process are introduced as well.The correctness of the system function can be verified by the analysis of detection results with different parameters.According to the analysis of resource occupation,power consumption and real-time performance of the signal processor system based on MPSo C design,the advantages of the designed system can be demonstrated.
