Light Detection and Ranging (LiDAR) of Unmanned Aerial Vehicles (UAVs)

The Defense Systems Information Analysis Center was asked to identify the latest research and development of LiDAR for use in detecting UAVs. LiDAR uses lasers with a lower wavelength compared to radio waves used by radar. This allows LiDAR to be more accurate and precise in detecting smaller objects with greater detail. Three-dimensional images are also easier to create based on the high-resolution images made in LiDAR. Current research is trying to develop and lower the costs of solid-state LiDAR technology for commercial and U.S. Department of defense (DoD) use. DSIAC staff identified advantages and disadvantages of using LiDAR compared to radar and DoD LiDAR applications and research.
