Abstract： Seismic data from desert and loess tableland areas often suffer from poor resolution and inferior imaging quality due to unfavorable source excitation conditions， strong noise interference，and severe high-frequency signal absorption and attenuation. To address this，a GT DS-5 Hz3×1 triple-core ultra-high sensitivity geophone was developed to capture high-frequency seismic signals. This was complemented by prestack processing techniques，including high-fidelity noise suppression，near-surface Q -absorption compensation，robust deconvolution，and Q -migration，forming an integrated“dual-high”（high-fidelity and high-resolution） seismic data processing system. When this technology was applied in the loess tableland area of the southern Ordos Basin，the data acquired using the GT DS-5 Hz3×1 geophone exhibited sharper responses at wave peaks and troughs， higher sensitivity，and enhanced identification capability for weak highfrequency reflections （the dominant frequency increased by ～3Hz ），leading to improved imaging. Combined with the high-fidelity， high-resolution processing workflow，frequency-division noise suppression was optimized， amplifying weak high-frequency signals and producing clearer reflection events，along with an expanded dominant frequency and effective bandwidth （dominant frequency increased by ～12Hz . Ultimately，high-quality seismic data were obtained，providing effective technical support for exploration in complex near-surface terrains.
