a Schematic diagram of determining the value of rk from the SPAC coefficient through the model function. The grey curve represents the model function of \({J}_{0}(rk)\). b SPAC coefficient curve affected by incoherent noise (broken line). rk is overestimated (i.e., rk′in the figure) in the rk range less than 2.6 when incoherent noise is present. The shaded regions in each diagram represent the rk range larger than 3.8 (i.e., out of the search range for rk)
