摘要： PROBLEM TO BE SOLVED: To solve the problems concerning a monitoring device in a ship or the like for which a radio wave radar or an infrared camera is used, that the radio wave radar is suitable for monitoring a long-distance large object but can not recognize a small object or a wooden or plastic object, and that the infrared camera can not recognize the distance to an object, because the camera is used in a passive system, and cannot observe an object except for that smaller than the visual range in the case of rain or fog, and can hardly detect an object existing on the sea surface for long time at night because of reduced temperature difference, since the detection is executed by the temperature difference, thereby making discovery of the obstacle. SOLUTION: In this method, the monitor device is constituted by combining the radio wave radar and a laser radar together, and a wide area is scanned by the radio wave radar, and when an object is detected in the near distance, switching to the laser radar is executed for detection and monitoring, to thereby enable to monitor from the long distance to the short distance or at nighttime, and to monitor even a wooden or plastic ship.

摘要： PROBLEM TO BE SOLVED: To provide a method for detecting and tracking a waterborne floating object which is capable of detecting and tracking general objects floating on water, including floating mines. SOLUTION: A pulsed laser beam is emitted from a laser radar toward the surface of water as an own ship 5 is navigated and a swivel base is revolved. A shutter is thereafter opened for a certain time to detect the beam reflected from a target 2 present within a predetermined detection area A1 to detect the target 2 and display it on a monitor screen. Further, in order for the target 2 to come to a predetermined position on the monitor screen, the swivel base is automatically revolved in the direction in which the target 2 moves, so as to automatically track the target 2.

摘要： PROBLEM TO BE SOLVED: To obtain a monitoring apparatus by which an object, to be recognized, on the ground can be recognized satisfactorily by using a laser radar. SOLUTION: In a laser radar, a pulse laser beam which is generated by a pulse laser generation device 1 is irradiated to the sky, and an object, to be recognized, existing on the ground and a distance up to the object to be recognized are measured. The wavelength of the pulse laser beam which is radiated from the pulse laser generation device 1 is set at 620 to 900 nm. Consequently, even in a state that fog is generated in the air, the dispersion efficiency of the laser beam irradiated to the air can be suppressed to be low to an extent that there is no problem practically. In addition, the wavelength of the laser beam becomes a wavelength whose lower limit cannot be recognized as visible light depending on the condition of the brightness of an environment under which it is irradiated. Even in the darkness, the object to be recognized can be recognized satisfactorily.
