| The complexity and diversity of the modern radar detection environment make the radar system become more and more complicated, which resulting in a significant increase in the amount of radar information. In meeting the high accuracy and accuracy of the processing results, people put forward higher requirements on the platform of high-speed data transmission and multi-tasking parallel processing capacity.One-dimensional DBF radar is an all-digital array scanning radar, and its receiving and transmitting beams adopt digital beam forming technology. Due to the feature of multiple beam forming, the signal processing device should have strong data processing and data transmission ability.Based on the realization of one-dimensional DBF radar information processing platform, this thesis studies the hardware composition and software implementation of the processing platform. Aiming at the development prospect of multi-core processor and multi-thread parallel technology, this thesis designed multi-threaded parallel processing scheme. The scheme focuses on the high speed, real-time and common performance of multi-core processor and multi-thread parallel processing,taking into account the advantages of processing large cache, large memory, large bandwidth, multi-core and multi-thread processing. It makes full use of multi-core processors performance, and study radar DBF real-time processing of the reconstruction thread pool technology, applying the thread pool reconstruction processing advantages in radar DBF processing. Through contrast experiment simulation, effectiveness and real-time processing is verified based on reconstructing thread pool technology of radar DBF. Finally, the multi-thread processing technology is applied to the research of radar information processing system, and the construction of radar information processing platform based on multi-thread parallel processing technology is realized. |
