A laser radar device formed in the following mode comprises a first signal sequence conversion unit (12) for converting a transmission signal generated by a transmission signal generation unit (1) into a first pulse signal sequence, a second signal sequence conversion unit (15) for converting a reception signal output from a reflected light reception unit (8) into a second pulse signal sequence, and a distance calculation unit (18) for calculating the distance to an object for distance measurement from the time difference between the time when transmission light was irradiated from a light irradiation unit (4) and the time when reflected light was received by the reflected light reception unit (8). A selection/discarding unit (19) calculates the degree of coincidence of the first pulse signal sequence and the second pulse signal sequence and selects/discards the distance calculated by the distance calculation unit (18) on the basis of the degree of coincidence. 以如下方式构成激光雷达装置，即，设置有：第一信号列变换部(12)，将由发送信号生成部(1)生成的
