Real-time representation of radar signals using Odroid XU4

Abstract

The representation system in modern radars is carried out by obtaining digital signals. In the case of tracking radars, the representation is updated in the order of tenths of a millisecond. In order to achieve to update the display in real time, the acquisition, processing and representation process must comply with the time requirement imposed by the radar. The objective of this work is the visualization of the information for a medium of this type in real time using the Odroid XU4 board. For their solution, the parallel programming method was used, through the creation of threads in the Qt Creator Integrated Development Environment and the use of the "cauce" segmentation parallel programming pattern. The result allowed an efficient use of computing resources, obtaining a decrease of the execution time and a greater acceleration with respect to the sequential variant.
