  Under the assignment of $a_0(1450)$ as the ground isovector scalar meson, the
strong decays of $a_0(1950)$ and $a_0(2020)$ are evaluated in the $^3P_0$
model. Our calculations suggest that $a_0(1950)$ and $a_0(2020)$ can be
regarded as the same resonance referring to $a_0(3^3P_0)$. The masses and
strong decays of $a_0(2^3P_0)$ and $a_0(4^3P_0)$ are also predicted, which can
be useful in the search for radially excited scalar mesons in the future.
