| Abstract: | Space-time adaptive processing(STAP),which is the key technology of airborne digital signal processing system,requires rigorous real-time constraints.Based on requirements of real-time STAP,a parallel processing system is realized for STAP,and it is composed of high-performance digital signal processing boards based on TS201.Through analyzing characteristics of STAP and system architecture,a system algorithmic model which is local serial and global parallel is presented,and high efficient ways are adopted for communication and synchronization during the course of model development.This model effectively enhances capability of load equa-lization for system.This system meet the real-time requirements and has good scalability. |
| Keywords: | DSP parallel processing STAP real-time platform parallel algorithmic model |
