%X The dynamic behavior of ring coupled Duffing oscillators driven by non-periodic signal is investigated, a phenomenon is discovered, which shows that when ring coupled Duffing oscillators are in the period-doubling bifurcation phase state and one of the oscillators is driven by pulse signal under certain parameter conditions, this oscillator and the other oscillators suddenly change from synchronization to transient non-synchronization and then rapidly return to synchronization, which is defined as transient synchronization mutation. This phenomenon can be used to accurately detect weak pulse signal in strong noise environments, which can further extend the weak signal detection range based on the Duffing oscillator.
