Relative radiation correction method for wide-view-field linear array CCD (Charge Coupled Device) camera

The invention relates to a relative radiation correction method for a wide-view-field linear array CCD (Charge Coupled Device) camera, which comprises the following steps: (1) selecting a uniform scene image; (2) dividing sub view fields by dividing detection image elements of the linear array CCD camera into different view fields by separating the view field angles of the wide-view-field linear array CCD camera at preset angular intervals; (3) calculating the widths of different sub view fields and the number of the contained detection image elements; (4) calculating an average value of the detection image elements DN in each of the sub view fields and calculating a yield value of the detection image elements in each of the sub view fields, according to the obtained number of the detection image elements; (5) on the basis of the sub view fields at the angular intervals, re-dividing the sub-view-fields into different sub-view-field areas at equimultiple angular intervals according to the multiple of the angul
