- WHISPER (Waves of HIgh frequency and Sounder for Probing of Electron density by
Relaxation) is one of the five wave instruments present on board each of the
four CLUSTER spacecraft.
It measures, in the 2 - 80 kHz range, the electric field fluctuations issued
from distant or local sources.
By operating a relaxation sounder, an active radio technique, the frequency
position of the plasma resonance is identified, leading to the reliable
measurement of the absolute density of the total electron population.
