The measurement of hadronic cross sections, especially at low centre-of-mass energies, is currently attracting a lot of attention due to the role these measurements play in the theoretical evaluation of the anomalous magnetic moment of the muon. The KLOE experiment at the DAPhiNE phi-factory in Frascati aims at a measurement of the cross section of the dominant process e(+)e(-) --> pi(+)pi(-) at energies below 1 GeV exploiting the radiative return from the phi to the rho and omega mesons. This method has systematical errors completely different from previous measurements. The method of the measurement as well as the current status of the analysis axe presented.
