Periodically driven non-Hermitian systems have attracted a lot of attention due to their intriguing topological phases. In this work, we propose a periodically driven non-Hermitian one-dimensional system, which features rich Floquet topological phases. The non-Hermitian Floquet topological phases are characterized by a pair of topological winding numbers, and the non-Hermitian system demonstrates a bulk-edge correspondence.
