• aeromagnetic anomaly
• potential field
• downward continuation.
• equivalent source
• boundary element method

Combining the equivalent source and the boundary element method, we downward continue the aeromagnetic anomaly from the flying altitude to the terrain, in order to increase the amplitude of magnetic anomaly and to decrease the probability of missing magnetic anomaly. The model test shows that the result from this algorithm accords well with the analytic solution. A practical example is given.
