In this paper a new data acquisition and analysis method for EISCAT (European Incoherent SCAT ter ) incoherent scatter radars are presented. The system allows storing the incoherent scatter radar signal itself instead of its autocorrelation function estimates. Samples of scattered signals and transmissions are stored in a single data stream on hard disk. This solution has great benefits; e.g. the ground clutter can be eliminated with only a small loss in statistical accuracy, and the true phase of the transmitter in phase coded experiments can be measured. In data analysis a very flexible signal processing can be applied.
