Adaptación terrestre de un radar meteorológico aerotransportado mediante decodificación ARINC-453

This paper presents the development of a tactical ground-based system based on the reuse of a decommissioned airborne weather radar. The study addresses the electronic and software adaptation of a Doppler radar originally designed for aeronautical applications, focusing on the decoding of the ARINC-453 communication protocol and the reconstruction of radar video data for ground-based operation. The proposed methodology includes the functional analysis of the original radar, the design of a data acquisition interface, the implementation of a signal decoding algorithm, and the experimental validation of the decoded information through digital processing and graphical visualization. The results demonstrate accurate interpretation of radar data, stable system operation, and functional equivalence with the original airborne display outputs. The main contribution of this work lies in the technical validation of repurposing airborne weather radars as low-cost, high-capability ground-based systems for tactical meteorological monitoring.
