The invention discloses a trigger circuit for on/off target adaptive identification. The trigger circuit is applied to a net target speed measurement system. The trigger circuit comprises an optical coupler, a first trigger, a second trigger, a double-path AND gate and an OR gate, wherein the input end of the optical coupler is connected with the net target output end of the net target speed measurement system, the output end of the optical coupler is connected with the input end of the first trigger and the input end of the second trigger, two reset signal ends of the first trigger are connected with the clock end of the second trigger, and the input end of each AND gate of the two-way AND gate is connected with one output end of the first trigger and one output end of the second trigger. The two output ends of the two-way AND gate are respectively connected with the input end of the OR gate, and the output end of the OR gate outputs a trigger signal. The trigger circuit can output pulse signals under the co
