The purpose of this study is to detect accurately the target in the image which is measured by the Imaging Laser Radar System using the high power LD. The Imaging Laser Radar System is the active imaging system, which transmits the laser beams and detects the reflected light. And, the Imaging Laser Radar System can obtain the range image in addition to the intensity image, simultaneously. In this paper, we research and develop the Imaging Laser Radar System. Firstly, we construct the Imaging Laser Radar System to measure the target at a distance of 50m from system. And, we obtain the intensity image and the range image, simultaneously. Secondly, we discuss the relationship between the target detection probability and the number of false alarms of the binary coded image. Then, we show that the range image has the higher detection probability and lower number of false alarms than the intensity image. According to the optical properties, the intensity and range image can simply be merged to obtain 3-D image using the data fusion algorithm. Thirdly, we discuss the relationship between the target detection probability and the number of false alarms of the binary coded 3-D image. Then, we show that the 3-D image has lower number of false alarms and higher detection probability than the range image.
