LISA (Laser Interferometer Space Antenna) is a proposed space mission, whichwill use coherent laser beams exchanged between three remote spacecraft todetect and study low-frequency cosmic gravitational radiation. In the low-partof its frequency band, the LISA strain sensitivity will be dominated by theincoherent superposition of hundreds of millions of gravitational wave signalsradiated by inspiraling white-dwarf binaries present in our own galaxy. Inorder to estimate the magnitude of the LISA response to this background, wehave simulated a synthesized population that recently appeared in theliterature. We find the amplitude of the galactic white-dwarf binary backgroundin the LISA data to be modulated in time, reaching a minimum equal to abouttwice that of the LISA noise for a period of about two months around the timewhen the Sun-LISA direction is roughly oriented towards the Autumn equinox.Since the galactic white-dwarfs background will be observed by LISA not as astationary but rather as a cyclostationary random process with a period of oneyear, we summarize the theory of cyclostationary random processes and presentthe corresponding generalized spectral method needed to characterize suchprocess. We find that, by measuring the generalized spectral components of thewhite-dwarf background, LISA will be able to infer properties of thedistribution of the white-dwarfs binary systems present in our Galaxy.Comment: 14 pages and 6 figures.
