Numerical validation model and results for one-step iteration: a Models of five different positions; the order from left to right is Targets 0–4, respectively. Perturbation conductivity images of Targets 0–4 using b DLS under SNR = 60 dB, c SC under SNR = 60 dB, d DLS under SNR = 80 dB, e SC under SNR = 80 dB. For each image, the color bar represents the range of the conductivity change, and the numbers represent the maximum range of change. The unit is S/m
