Abstract [en]

In this thesis data taken by the EISCAT Svalbard Radar during the International PolarYear have been analyzed. The radar data have been searched for anomalous radarechoes. These radar echoes appear in an altitude range between 200 and 300 km, showa strong enhancement of the backscattered power and are limited in altitude to tensof kilometers. These anomalous radar echoes also show a distinct zero Doppler shiftedpeak in the ion line spectrum. The power prole of the data have been visually inspectedto identify the anomalies. The data have then been analyzed using a Matlab programcalled GUISDAP in order to get basic plasma parameters. It has been found that thereis a high occurrence of these anomalies during particle precipitation and at a certainE-region electron density peak more than 40 % of the data contains these anomalies.
