Distance gating imaging system for improving imaging resolution based on Tail-Gating technology

The invention relates to a distance gating imaging system for improving imaging resolution based on a Tail-Gating technology. The distance gating imaging system comprises an emission light source module; a distance measurement receiving module, used for collecting and filtering echo light signals reflected by the underwater target, converting the echo light signals into electric signals and forwarding the electric signals to the control and processing module; an imaging receiving module, used for receiving an optical signal which is reflected by the underwater target and contains target imageinformation and forwarding the optical signal to the control and processing module; and a control processing module, used for setting the parameters of the transmitting light source module, setting the parameters of the distance measurement receiving module, controlling the distance measurement receiving module to synchronously acquire echo signals reflected by an underwater target, calculating the distance of the underwa
