  A detailed study is presented of elastic WW scattering in the scenario that
there are no new particles discovered prior to the commissioning of the LHC. We
work within the framework of the electroweak chiral lagrangian and two
different unitarisation protocols are investigated. Signals and backgrounds are
simulated to the final-state-particle level. A new technique for identifying
the hadronically decaying W is developed, which is more generally applicable to
massive particles which decay to jets where the separation of the jets is
small. The effect of different assumptions about the underlying event is also
studied. We conclude that the channel WW -> jj+l+nu may contain scalar and/or
vector resonances which could be measurable after 100 fb^(-1) of LHC data.
