Abstract:Using the Reduction-to-the-pole (RTP) Algorithm-Error (A-E) equation as a theoretical tool,The authors conduct mechanism analysis and function positioning of three wave-number-domain RTP methods for magnetic anomalies at low latitude (RTP-L). The suppression RTP method is ineffective for quantitative interpretation,but effective for qualitative interpretation of magnetic anomalies at low latitude. Theoretically,the inversion RTP method is applicable for quantitative interpretation of magnetic anomalies at low latitude,but it demands that the unknown data outside the calculation window should be well modeled,so it is not practical because measured data are not satisfying. The shift sampling RTP method may be applicable for quantitative interpretation of magnetic anomalies at low latitude,but the data (grids) in the magnetic declination direction can't be more than 64 and the data accuracy should not be less than 0.2%.
