High precision and strong anti-interference performance positioning technology for multi-port synchronous detection using electroacoustic joint detection

In order to understand the high-precision and strong anti-interference performance positioning technology of electro acoustic joint detection, research on multi-port synchronous detection of electro acoustic joint high-precision and strong anti-interference performance positioning technology has been proposed. This paper first introduces the performance and development architecture of TMS320C6678, and explains the peripherals to be used. Secondly, the specific process of the time difference frequency difference joint positioning algorithm in multi-core DSP parallel operation and the workflow of the entire system was introduced. Finally, the system was tested and analyzed, mainly focusing on the testing of positioning time and accuracy, as well as the impact of multi-core and single-core positioning. Through analysis, it was found that the joint positioning of time difference and frequency difference can be processed on multiple cores to achieve faster and more accurate target positioning. This verified that the processing speed of multiple cores is better than that of a single core, and finally verified the rationality and feasibility of this system.
