  We investigate soft gluon radiation in hadronic $t\bar t$ production. By
taking the top quark decay properly into account, we are able to study the
interplay of radiation both before and after the decay of the top quarks. The
production--decay and decay--decay radiative interferences depend sensitively
on the relative size of the gluon energy and the decay width. Radiation
patterns for various production mechanisms are compared.
