The automatic recognition of range-spread target is based on its range profile. When obtaining its range profile by using synthetic wideband radar signal, the different-range scatters would be overlapped because of the range-doppler coupling effect. The overlapping effect affects the ability of the automatic recognition algorithm. According to this, based on the Linearly Modulated Stepped Frequency (LMSF) radar signal, coherent processing of range profiles to obtain zonal image of range-spread target is proposed in this paper, which avoids the overlapping effect. The theoretical model of the zonal image of range-spread target is presented, the signal processing flow is derived, and the simulation result of zonal image is also given in this paper.
