CONCEPT OF A RESONANT-ANTENNAE OBSERVATORY FOR GRAVITATIONAL-WAVE BURSTS

We show how, combining their outputs, at least six resonant bar antenn ae give with isotropic sensitivity the amplitude, polarization, and di rection of propagation of a burst and test for two distinctive propert ies of the Riemann tensor: transversality and tracelessness. If not lo cated at the same site, to exert the two vetoes, the burst arrival tim es on three antennae must be known; we show how to determine them. The n in addition the propagation of the burst at light velocity is tested .
