Abstract: The present invention relates to a laser-radar optical system which includes: a transmission unit for emitting a transmission signal to a target in the front through a plurality of light-emitting lasers; an objective lens for refracting and focusing a reflection signal reflected from the target; a receiving optical fiber bundle cable for receiving the focused reflection signal through the objective lens and making the signal into single signal; a scaling optical system which is formed in one side of the receiving optical fiber bundle cable for reducing the intensity of the reflection signal emitted from the receiving optical fiber bundle cable; and a single detector for receiving the reflection signal with reduced intensity emitted through the scaling optical system. A laser-radar optical system for receiving spatially-separated multiplexed signal with a single detector which is capable of realizing a small-sized transmission and reception optical system is provided by using the transmission optical fiber bundle connector, receiving optical fiber bundle connector, scaling optical system and single detector.

Abstract: The present invention relates to a ghost image elimination method of a laser radar system which comprises the steps of: setting up an echogenicity criteria of a not received first channel by calculating a representative value of a target distance investigated by a first channel laser pulse in a multi-channel laser; obtaining a number of echo signals not received at last by comparing the calculated representative value of the target distance and a smallest unit of a distance difference of a ghost image; and correcting a distance error of the not received echo signal by assigning an echo signal distance value to the channel based on the number of echo signals not received. Thereby the ghost image of the laser radar that can occur in the multi-channel laser based radar is effectively removed.
