摘要	Being influenced by the high temperature, high humidity on the sea surface, the volume of the shipborne optoelectronic equipment and the output power of laser ranging, the power of the laser range finder is greatly reduced in such sea-sky environment; especially, the ability for detecting long-range target is near zero. The encounter ability of the shipborne optoelectronic equipment that relies on laser ranging to obtain the range information is weakened greatly. Here in the paper, under the inertial navigation platform we use the filtered speed feed-forward technology to realize the TV closed loop stable tracking, and combine the "side angle orthogonal" intersection measurement technology to realize the target distance measurement in ship-surface environment. The method has already been applied to the XX project successfully. There are two steps for realizing this technology. First, when the target appears simultaneously in the fields of sight of two optoelectronic tracking equipment and the image contrasts meet the threshold requirement for the image extraction, the speed data of the INS calculated with the CA filter model least-squares method is feed-forwarded to the speed loop, which is combined with the TV offset information to achieve the TV tracking closed-loop control. Secondly, the target data information is processed using two optoelectronic tracking instruments with the side-angle orthogonal method, and the distance information is obtained. The experimental results verify that the technology can realize the long distance target ranging; and the ranging distance can reach up to 30 km or longer when the ranging accuracy is not larger than XX m under the sea-sky environment, which is much larger than that of common shipborne optoelectronic ranging system. We can come to a conclusion that the passive ranging of the long-range ship-based optoelectronic equipment is realized with the side-angle orthogonal intersection method; especially, the ranging ability for low-altitude sea-skimming targets is improved. Under the state of the silent radar, the three-dimensional information can be used to directly guide the weapons to precisely track and attack the incoming targets.
