Abstract: Provided is an apparatus and a method for estimating a specific differential phase using dual-polarization variables. The apparatus includes: a memory for storing a specific differential phase estimation program for estimating a specific differential phase using the dual-polarization variable of an observation data received from a dual-polarization radar and a self-consistent calculation method; and a processor including: a horizontal attenuation calculation unit; a differential phase calculation unit; a cost function calculation unit; and a specific differential phase calculation unit.
