Abstract

The invention discloses a submarine navigation monitoring system based on laser polarization detection. The submarine navigation monitoring system comprises an underwater part 1 and a ground part 2, wherein the underwater part comprises a submarine navigation system, a two-axis turntable, a scanning mechanism 19 and a submarine sound signal transmission system 5; the ground part comprises a submarine sound signal receiving system 30 and monitoring equipment 35.The main principle is that laser light becomes partially polarized light or linearly polarized light after being reflected through a man-made object, and the polarization property of the reflected light contains a variety of information of the object. As the texture structure, the surface state and the material type of the underwater man-made object are different from the texture structure, the surface state and the material type of a natural object, reflected laser light with different polarization properties are obtained, images with different degrees of polarization are extracted through a polarizer arranged at the front of a video camera, and the man-made object is separated through image processing. The submarine navigation monitoring system can assist the sonar technology in effectively detecting and recognizing submarines, torpedoes and other military targets, thereby being a detection means which is high in distinguishability, sensitivity and efficiency.

Description

technical field [0001] The invention relates to a submarine monitoring system for monitoring underwater man-made objects, in particular to a submarine monitoring system for laser polarization detection. Background technique [0002] As the Navy's strategic mission shifts from deep-sea confrontation to maintaining a presence in potentially hostile littoral waters, mine warfare and mine countermeasures have become increasingly important. At the same time, the silence technology of modern submarines is getting more and more advanced, and a single sonar detection technology can no longer meet the needs of modern warfare. Subsequently, detection using light has gradually been applied to military detection. [0003] Polarization detection technology is a new remote sensing detection technology developed in recent years. As we all know, any target on the earth's surface and in the atmosphere will produce characteristic polarization determined by its own characteristics in the pro...
