摘要： A coherent laser radar system includes a pulsed laser oscillating a pulsed laser beam which is split into two parts by an optical divider. A first part of the two is transmitted as a transmitted beam via a beam splitter. A second part is supplied to a delay line via a coupling optics and others to be delayed by a predetermined time as a local beam, and is incident onto an optical coupler. The received beam from the target is incident onto the optical coupler via a scanning optics and so on. A photodetector carries out the coherent detection of the light beam coupled by the optical coupler. A signal processor computes a target velocity and the like from a signal generated by the detection and converted into a digital signal by an A/D converter. This makes it possible to solve a problem of a conventional system in that the system configuration is complicated and expensive.

摘要： An air traffic control support system comprises: a wake turbulence detecting unit adapted to detect a wake turbulence occurring in a runway sky due to taking off or landing of an aircraft; a decay time predicting unit adapted to predict decay time of the wake turbulence; a weather information acquiring unit adapted to acquire weather information in the surroundings around the runway; and a display unit adapted to display the decay time, wherein the decay time predicting unit predicts the decay time of the wake turbulence detected by the wake turbulence detecting unit on the basis of the weather information.

摘要： Reducing blind spots of a laser radar observing wake turbulence is required for detecting efficiently the wake turbulence which appears behind the main wings of an aircraft and affects the flight of other aircraft. A first laser radar a and second laser radar each emit a laser beam from different positions. A signal processing device produces wake turbulence information based on the reception signal of the first and second laser radar. Further, the signal processing device specifies wake turbulence information for producing display data either by making a composite of wake turbulence information of two laser radar whose observation areas do not overlap each other or by selecting the larger value of wake turbulence information from two laser radars whose observation areas overlap each other and produces display data for indicating wake turbulence information on monitor display based on the specified wake turbulence information.
