A semi-phenomenological approach to describe the evolution of Fermi surface (FS) and electronic structure with doping is presented which is based on the spin-fermion model. The doping is simulated by a frustration term in the spin Hamiltonian and the complex internal structure of the spin-polaron quasiparticle is taken into account by a superposition of spin-polaron states with different radii. By calculating the spectrum, the spectral weights and the FS we find a rather drastic change of the electronic structure with doping which explains many photoemission data, i.e. the isotropic band bottom and the remnant FS of undoped cuprates, the large FS and the extended saddle point of optimally doped compounds and the pseudogap in the underdoped samples.
