  Stochastic gravitational wave background produced by a stationary coalescing
population of binary neutron stars in the Galaxy is calculated. This background
is found to constitute a confusion limit within the LISA frequency band up to a
limiting frequency $\NUlim{}\sim 10^{-3}$ Hz, leaving the frequency window
$\sim 10^{-3}$--$10^{-2}$ Hz open for the potential detection of cosmological
stochastic gravitational waves and of signals involving massive black holes out
to cosmological distances.
