Abstract
A coherent OFDR model that enables to extend the dynamic range is proposed. π/2 phase shifting technique is involved in the proposed system in order to obtain complex interference signal. The obtained complex signal is processed to remove DC and mirror peaks in the frequency domain. The simulated results show the enhancement of dynamic range.
