Abstract
The purpose of the present invention is to achieve highly accurate detection of obstacles even in adverse weather environments, particularly environments in which a scatter phenomenon caused by fog or the like occurs. A target signal processing unitcalculates a cross-correlation function between split reference light from a light source unit, and reflected light from a target T, said reflected light being obtained using split signal light from the light source unit. An estimation unitestimates scattering characteristics of propagation paths of the signal light and the reflected light. A correction processing unitexecutes, on the basis of the scattering characteristics estimated by the estimation unit, prescribed correction processing of the cross-correlation function calculated by the target signal processing unit
