Abstract


Netted radar is a major trend of the development of the radar today, has important implications for improving the system's target detection and anti-jamming capability. The netted radar signal processing capabilities of the system put forward higher requirements. To make networking radar to survive and improve their ability to complete large-scale data collection and processing, it must have a strong signal processing performance. Therefore, to build high-performance signal processing systems, to meet the networking needs of the radar signal processing, is imminent an important work. Parallel signal processing technology is an important way to improve the system signal processing capabilities, more and more widely used in modern radar and communication systems. It can provide powerful digital signal processing capability, a very clear role in the field of radar signal processing. Building scalable parallel processing system through the use of multi-chip high-performance signal processor, you can change the system structure based on a specific algorithm, flexible configuration system resources and improve the efficiency of signal processing. In this paper, based on multi-chip ADSP TS201S high-speed parallel signal processing system design and debug. On this basis, the field of radar signal processing system used in networking, and algorithm design and task allocation. The main work of this paper include the following aspects: 1, parallel signal processing technology and its applications. First study the main factors constraining system performance parallel signal processing system; then analyze distributed the netted radar data processing technology; parallel processing and MATLAB simulation and track association and fusion algorithm. Through the study of specific technology, hardware and software design are a wide range of requirements. 2, the parallel signal processing system is designed and implemented. Parallel signal processing system is achieved through the use of multi-piece ADSP TS201S chip, hardware, and complete the communication between the various modules of the system debugging. Parallel signal processing systems are designed to have a large-scale cache, structural flexibility, scalability and other features. 3, the system works. Distributed netted radar data associated with the fusion algorithm, and has been applied in the hardware system. Depth analysis algorithms, parallel structure, effectively the task divided, so that system resources are fully utilized. By comparing simulation results show that the parallel processing technology to improve the system real-time has a great advantage.
