Research On Autonomous And Controllable Missile-Borne Signal Processor

The research of autonomous controllable weapons and equipment is a major topic that needs to be tackled in the new era of national defense and military construction.The current degree of informationization of the military weapons and equipment has reached a new level,and improving the level of autonomy and system integration is an important direction for future research.Due to the special working environment and the limitation of space and power consumption,most of the missile-borne signal processors adopt the heterogeneous reconfigurable signal processing architecture,which has the characteristics of high performance and miniaturization.It is of great significance to carry out the research on autonomous and controllable missile-borne signal processor for integrating highperformance autonomous controllable devices and accelerating the process of localization of weapons and equipment in China.The main work accomplished in this thesis is as follows.Based on the heterogeneous reconfigurable computing architecture and using the 3U-VPX hardware standard,an autonomous,controllable,multi-functional and standardized missileborne signal processing machine with multi-module collaboration has been designed.The specific functions of each module have been divided according to the characteristics of the missile-borne signal processing task.The selection of domestic autonomous controllable devices has been carried out,so that the whole machine has reached 100% localization.The design difficulties related to the autonomous controllable unit module were overcome,and the 4-channel signal acquisition board,4-channel signal generation board,signal processing board and main control board were designed and developed.The key functions and performance indexes of the signal processor are tested.The transmission rate of high speed serial bus between signal processing nodes,the significant bits of signal acquisition of domestic ADC chip,the output signal bandwidth and spurious free dynamic range of domestic DAC chip,and the dynamic reconstruction function of YHFT-DSP signal processing node are tested.The target test and performance analysis of the signal processor are completed.For real-time signal processing tasks with high precision,high complexity and high data bandwidth,the application scenario experiment verification based on autonomous controllable missile borne signal processor platform is completed.Focusing on the application of high precision and high complexity multi-core signal processing,the pulse Doppler radar signal processing based on YHFT-M6678 DSP is realized.Focusing on the application of high data bandwidth and high real-time signal processing,the SAR echo realtime simulation based on Fudan Micro-electronics JFM7XV690 T FPGA is realized.The experimental results show that the heterogeneous signal processing mode of the processor can give full play to the performance of autonomous controllable signal processing devices,and show the great application value of autonomous controllable signal processor.
