Phase-coded Radar Signal Processing Based On Multi-core DSP In 6678

Currently various radar systems, such as airborne radar, shipboard radar, spaceborne radar, ground radar, if you want to achieve high overall performance, you need a very strong signal processing and data processing capabilities. Signal processing techniques involved in radar systems generally need large volumes of data, complex processing tasks, repeated large amount of computation and real-time processing and so on.In this paper, we combine the application of radar systems to discusses the radar signal processing solutions based on multi-core DSP6678and sys/bios real-time operating system. First, the two-phase encoded signals emitted used herein were designed and simulation, and the features of two-phase encoded signals were analysis from the time domain and frequency domain. Secondly, the radar signal processing to be performed were discussed and simulation. Then gives a brief introduction and6678DSP chip development process, the DSP thread, EDMA3, multicore communication module has been designed, and then we realize the various modules based on the DSP, and gives the realization results and compared with the simulation to verify the feasibility of implementation.This paper discusses the system commissioning process at the end of the paper, first designed Platform and TargetConfiguration which are debugging required documents, and describes its role in the system. After that we commissioning of the EDMA3and multicore communications module respectively, verify its feasibility, and calculate the amount of time spent throughout the process to verify the real-time nature of the system.
