This invention relates to the field of radiation detection technology, specifically to a high-precision detection method and system for ionization chambers based on gas detectors. The method determines a spatial distribution basis matrix by analyzing the correlation of current values ​​in different ionization chamber units, and extracts the spatial linkage characteristics of the detector array during movement. It utilizes the local mapping characteristics of non-radiative zone units in the basis matrix and introduces a regularization term to determine the derivation matrix. Simultaneously, it determines an edge reference signal vector based on the historical relative deviation of the original current in the non-radiative zone units, and couples this vector with the spatial distribution basis matrix and the derivation matrix to determine the overall array interference estimation vector. Finally, it uses the relative deviation between the original total current vector and the overall array interference estimation vector to determine the dose response signal vector, accurately identifying the dynamic mechanical interference current that fluctuates in real time with movement. This results in higher accuracy in detecting radiation dose distribution based on the dose response signal vector.
