Visualizador digital de un radar de seguimiento empleando Raspberry Pi 4

Abstract

A radar display is an electronic device used to present a continuous graphic image, which allows easy understanding of the relative position of detected objects. Modern displays perform the representation by obtaining digital signals. Most of the available tracking radar displays are based on analog technology. They are high consumers of electrical energy, have a large volume and weight, their parts are obsolete and it is impossible to acquire spare parts from the international market. These displays are subject to long maintenance periods, as they are unstable during operation. The objective of this work is to design and implement a digital display of radar signal information that complies with the update period of a tracking radar. The proposed solution uses the Raspberry Pi 4 single board computer and the software was developed in the Qt Creator cross-platform development environment. In addition, parallel computing was used to achieve the reception, processing and representation of the data, complying with the update period of the tracking radar information. This allowed to reduce the software execution time and to comply with the radar update period, unlike the sequential version where the time restriction was not met. As a result, a technological replacement of the analog display system, which has low power consumption, cost and size, was obtained.
