DISPLAY FOR IONOSPHERIC SOUNDING SYSTEMS

DISPLAY RANGE MARKER PROCESSOR

DISPLAY RANGE MARKER PROCESSOR A variable range marker processing device for use with a PPI radar with digitized video displayed in non-real time. The position of the range marker is initially operator determined by rotation of a knob mechanically linked to an optically encoded disc. Optical sensors produce a digital output indicative of tile disc rotation angle and range mark position as a distance from the center of the radar display screen. A counter is preset with the digital output at the start of each sweep and decremented once each range cell until a count of zero is reached at which time an unblanking pulse is produced. A numeric display of range is produced by dividing the number of range cells to the range mark by the range setting, scaling according to chosen units of measure, and displaying the result with a LED display, the computations being performed by a processor controlled by a permanently programmed memory. The range mark stays on target as the range scale is changed.

Method and apparatus for displaying radar video registered with computer generated data on a television monitor

A method and apparatus for use in air-traffic control are described for maintaining substantial registration alignment between radar video signals and associated computer generated data on a television monitor. It is a requirement of the monitor display that the radar video, such as raw radar, map video, etc., be displayed with a long time constant to show the history of the radar trails. Simultaneously, the associated computer generated data, such as vectors, alpha-numerics, etc., must be displayed properly registered with the radar video on the same monitor with a short time constant. This is necessary to avoid smearing, since the latter data moves on the monitor screen as the radar pattern changes. In accordance with the present invention, the radar and computer data are combined into a single cathode ray tube, photographed by a pair of vidicons having different time lag characteristics, and the images of the latter combined on a television monitor.

SENSING METHOD FOR SKEIN OF BIRDS

PURPOSE: To sense a skein of birds irrelevantly to meteorological conditions and whether it is day or night by comparing a reflection image based upon detection pulses of an S band with a reflection image based upon detection pulses of an X band.

Object detection method

A dummy target is set in a direction which is the same direction as that of a detected target and at the position whose distance is double that of the detected target; a second-order wave target detection area is set in the predetermined area including the position of the dummy target; the target detected in the second-order wave target detection area is judged as being a second-order wave target; a interpolated target is set in the direction which is the same as that of the second-order wave target, and at the position whose distance is half that of the second-order wave target; a fundamental wave target detection region is set in the predetermined area including the position of the interpolated target; and the interpolated target is outputted as a fundamental wave target in the case where no fundamental wave target is detected in the fundamental wave target detection region.
