Microwave Transmission of Pressure Sensor Signal Through Explosive Fireballs
Résumé
In this paper, we use microwaves for wirelessly transmitting the pressure signal delivered by sensors placed inside high explosive fireballs. It is demonstrated that the modulation of a microwave carrier frequency by pressure signal may be transmitted through fireballs without significant distortion, spectral filtering and attenuation of pressure signal. For experimental validation purpose, we show that the proposed wireless measurement of the pressure variation inside fireballs is in very good agreement with that obtained from a wired transmission, even if aluminized explosives create fireballs
