Topography data experiment. (a) Interferogram. (b) Coherence map. (c) The unwrapped map for the CKFPU method. (d) The unwrapped map for the IACKFPU method. (e) The difference for CKFPU. (f) The difference for IACKFPU. (g) The difference histogram for CKFPU. (h) The difference histogram for IACKFPU. (i) The simulated unwrapped phase map using a relief DEM. (j) Misfit values along FD unwrapping path for the two methods. The blue and red lines are for CKFPU and IACKFPU, respectively.
