In the former paper, the authors described the results of simulation and fundamental ex-periments by using Frequency Diversity method which is a new data processing technique for Acoustic Fish Assessment System.
In this paper we discuss the results of real time prediction for Volume Scattering Strength which is measured in a short interval (10 seconds) by using the above equipment.
First we assume that Volume Scattering Strength x (t) is a Stationary Auto Regressive Process and predict them by linear combination of the previous setting of order M
??
Next we discuss the Coherency and Frequency Response Function between original data and prediction data in order to estimate the efficiency of prediction in the: Frequency domain.
Lastly we define the estimation function such as
??
and discuss relationshlp between ε and correlated-width.
