This study proposes a monitoring method for corrosion on reinforced concrete structure using inverse analysis approach. We define an inverse problem to identify the real part and imaginary parts of the concrete conductivity and the impedance between concrete and steel. The observation of the inverse problem is the electric potential on the concrete structure surface when the AC impedance measurement is performed. The observation condition, such as layout of observation point and type of observation, of the inverse is optimized. The optimization is achieved by minimizing the average of eigen values of a posteriori estimate error covariance matrix based on the Kalman Filter estimation algorithm and by sensitivity analysis of observations.
