Study on Terrain Navigation Technology for Cruise Missile Based on Laser Echo Waveform Matching

Terrain matching navigation cannot be implemented effectively for the cruise missile in the flat terrain area, which is very disadvantage for the selection of terrain matching area. In this paper, a new terrain navigation technology for the cruise missile based on laser echo waveform matching is studied. By extracting the characteristics of the laser echo waveform from the ground target and matching with the waveform data in the database, the attribute and location of the ground target are determined. The flight route of the missile can be further corrected according to the position of the target in the map. This technology can expand the selection range of terrain matching area, lower the requirement on the height fluctuation of the terrain and reduce the difficulty of planning terrain matching area for the cruise missile, and has a good military application value for improving the performance of cruise missile.
