A broad-band analyzer of the IME-HF instrument (“Instrument de Mesure du champ Electrique
Haute Frequence”) is being prepared for the TARANIS (Tool for Analysis of RAdiation from
lightNIng and Sprites) micro-satellite of the French space agency CNES. The spacecraft is based on
the MYRIADE series platform. It will be launched and on a Sun synchronous polar orbit at 700 km
altitude. TARANIS will carry a complex payload of six scientific instruments to study radiation and
from lightning and optical phenomena (Transient Luminous Events) observed at altitudes between 20
and 100 km (blue jets, red sprites, halos, elves). The scientific instruments onboard TARANIS will
detect electromagnetic radiation from very low frequencies up to 37 MHz, optical radiation, X rays
(with an aim to study the Terrestrial "Gamma-ray" Flashes), and energetic electrons.
The IME-HF instrument will record waveform measurements of fluctuating electric fields in the
frequency range from a few kHz up to 37 MHz, with the following scientific aims: (i) Identification of
possible wave signatures associated with transient luminous phenomena during storms; (ii)
Characterization of lightning flashes from their HF electromagnetic signatures; (iii) Identification of
possible HF electromagnetic or/and electrostatic signatures of precipitated and accelerated particles;
(iv) Determination of characteristic frequencies of the medium using natural waves properties; (v)
Global mapping of the natural and artificial waves in the HF frequency range, with an emphasis on
the transient events. The instrument will be also able to trigger and record interesting intervals of data
using a flexible event detection algorithm.
We have prepared a ground-based observational campaign with an identical high frequency
analyzer. After the launch of the TARANIS satellite this campaign will complement the observations
from space.
