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 \nu _ { lim } { } \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 .
