Type of experiment | The experiment consists on a sounder that can be in passive mode to measure
(via passive wave analysis) the natural wave emissions in high-frequency range, (4-80 KHz) or in active mode (emission of short pulses of sine wave during 1 millisecond and listenning to the electric field signal transmitted to the other antennas) to identify the plasma resonances and then the total electron density. |
