We present a new technique for underground imaging based on the idea of space-frequency filtering and
downward continuation of the observed airborne magnetic and electromagnetic data. The technique
includes two major methods. The first method is related to the downward analytical continuation and
is based on the calculation of the total normalized gradient of the observed field. The second method
is based on Wiener filtering and takes into account a priori information about typical AEM anomaly
shape from a possible target.
