Abstract
Apparatus and associated methods relate to controlling an explosive burst event of a ballistic ordnance, based on a ground surface topography mapped by a phased-array LIDAR system. The ground surface topography is mapped using an integrated photonics LIDAR system configured to: generate a beam of coherent light; non-mechanically steer a beam of coherent light over a solid angle about an ordnance axis; and detect the beam reflected from the ground surface. The integrated photonics LIDAR system is further configured to map the ground surface topography, based on a functional relation between an angle of the beam and a time difference between generating the beam and detecting the beam reflected from the ground surface. A timing and/or direction of the explosive burst can be controlled, based on the calculated ground surface topography, so as to advantageously realize a desired effect of the explosion.
