A-4 Skyhawk Aircraft Stealth Capacity Against L-Band Radar Based on Dynamic Target Detection
Autor: Renan Richter, Newton A.S. Gomes
Publikováno v: 2020 IEEE Radar Conference (RadarConf20).
The purpose of the paper is to analyze the A-4 Skyhawk aircraft stealth capacity as a function of its radar cross section (RCS) against an L-band monostatic radar (1 to 2 GHz). The article proposes a trajectory to a certain probability of detection,

Electromagnetic, morphological and structural characterization of microwave absorbers based on POMA/magnetic filament composites
Autor: João Paulo Barros Machado, Simone de Souza Pinto, Newton A.S. Gomes, Mirabel Cerqueira Rezende
Publikováno v: Journal of Magnetism and Magnetic Materials. 449:406-414
This study aims to combine dielectric and magnetic properties of different materials in an unique composite. For this, poly(o-methoxyaniline), POMA, was chemically synthesized in situ on magnetic metallic filaments (MF). The obtained composite was in
