A laser radar device and an object detecting method

Japanese Patent JP6012589

B2

A laser radar device includes: a projection part repeatedly performing processing of projecting measurement light that is of a pulsed laser beam to a predetermined monitoring area in a measurement period having a predetermined first length, the processing being repeated in c cycles (c≧2) in a detection period having a predetermined second length; a light receiver including n1 (n1≧2) light receiving elements and receiving reflected light of the measurement light in directions different from one another; a selector selecting light receiving signals of the n1 light receiving elements in each measurement period and output n2 (n2≧2) light receiving signals; a sampling part sampling the light receiving signals output from the selector s (s≧2) times every time the measurement light is projected; and a detector performing processing of detecting an object in a detection-period-based period based on sampling values.
