Modeling and Simulation of Interference Between Aircraft Radar Altimeter and 5G-C Band Transmissions Along with Implementation of Proposed Solution

This paper presents an in-depth study of interference between aircraft radar altimeters and 5G C band transmission a critical issue in the aviation industry. The modeling and simulation research focuses on the interference effect, its analysis, and the development of a viable solution that requires the least certification overhead. The interference between aircraft radar altimeters and 5G C band transmission poses a significant threat to the safety and efficiency of aviation operations. The radar altimeter, vital for navigation and control in aircraft, provides accurate altitude readings above ground level, which is indispensable for secure landing. However, the advent of 5G technology and its operation in the C band spectrum has raised concerns about potential interference with radar altimeters. The study employs a robust technical approach to model and simulates the interference scenario in Simulink. The simulation model is designed to accurately represent the real-world scenario of the interference between the radar altimeter and 5G C band transmission. The model is then subjected to rigorous analysis to understand the nature and extent of the interference. The research further delves into the development of a solution to mitigate the interference. The proposed solution is implemented in Simulink, allowing for a comprehensive evaluation of its effectiveness. The solution involves the regulation of the distance of the 5G-C band tower from the airport runway in order to avoid interference from the 5G-C band transmission, thereby ensuring the integrity of the radar altimeter readings. The results from the simulation and implementation of the proposed solution provide valuable insights into the interference issue and its potential solutions. The study contributes significantly to the ongoing discourse on the coexistence of aviation systems and 5G technology.
