The invention is a distance strobe type laser 3D imaging radar system, relating to a distance picture imaging radar system, where the beam emitted by pulse laser is shaped by optical transmitting aerial and then irradiate an object, the echo beam reflected from the object gets through optical receiving antenna and filter plate to light input end of stroke type ICCD, synchronous control circuit controls multistage variable delay generating circuit to output various delay signals to input end of multichannel switch and controls grid stroke of the stroke type ICCD. And adopting distance stroke for 3D imaging can adopt a high-power pulse laser and the existing stroke-type image intensifier. And it has strong device universality, easy to implement and having higher distance resolution.
