In this Letter we introduce a new kind of coherent particle production mechanism called dual coherent particle emission (DCPE) as generalized two-component Cherenkov-like effect, which takes place when the phase velocity of emitted particle v_{ Mph} and the particle source phase velocity v_{ B_1ph} satisfy a specific DCPE condition: v_{ Mph} <= v_{ B_1ph}^{ -1}. The general signatures of the DCPE in dielectric, nuclear and hadronic media are established and some experimental evidences are presented.
