Abstract :
This paper proposes a novel extremely low frequency (ELF: 3 - 300 Hz) radar for locating and characterizing ionospheric anomalies within ~100 km of the Earth´s surface. Employing a well-characterized controlled ELF source (as opposed to natural sources having a random occurrence and random properties), the proposed radar could provide continuous, inexpensive monitoring capabilities of the ionosphere within ~100 km of the Earth´s surface. For this study the recently developed three-dimensional (3D) geodesic whole-Earth electromagnetic wave propagation model based upon the finite difference time domain (FDTD) solution of Maxwell´s equations is used
