Proton radiography is a common diagnostic technique in laser-driven magnetic field generation studies. It is based on measuring proton beam deflection in electromagnetic fields induced around the target with the help of radiochromic film stacks. Unraveling information recorded in experimental radiographs and extracting the field profiles is not always a straightforward task. In this paper, some aspects of data analysis by reproducing experimental radiographs in numerical simulations are described. The approach allows determining the field strength and structure in the target area for various target geometries.
