P. Ilavarasan et al., NATURAL RESONANCE EXTRACTION FROM MULTIPLE DATA SETS USING A GENETIC ALGORITHM, IEEE transactions on antennas and propagation, 43(8), 1995, pp. 900-904
This paper presents a scheme to extract the natural frequencies of a r
adar target from multiple data sets using a genetic algorithm techniqu
e (GAT), This technique prevents the extracted damping coefficients fr
om being positive, as often happens with low signal-to-noise ratio dat
a, by restricting the search parameters of the damping coefficients to
be negative values. The GAT does not require an initial guess, unlike
the constrained E-pulse technique (GET). The results from the GAT com
pare well with the CET (with much less effort required) and also with
such established techniques as the pencil-of-functions method and the
nonlinear least-squares technique.
