Patent ES-416255-A1 (ES)
Title: Radar and like echo-display apparatus
IPC: G01S7/04
Filed: 1973-06-25
Abstract: A ship's radar includes an electrically energized image-retaining panel that has a surface which is exposed continuously to a relative-motion plan-position echo-display on a cathode-ray-tube screen via a relay lens and a frequency-selective optical filter, so as to retain and display from the surface, time-varying images of the display, superimposed upon one another. The panel, which displays the cumulatively retained images in light of a different wavelength from that emitted by the cathode-ray-tube screen, is mounted on a table of a carriage mechanism to be moved relative to the cathode-ray tube in accordance with the ship's movement. The table is carried on a caged ring of balls that are sandwiched in the carriage mechanism between two independently-mounted friction plates that are urged together under spring pressure. One plate is driven along a straight line in accordance with speed measured by the ship's log and the other is driven from the ship's compass system to turn with change of direction of the ship, so that there is transmitted to the table via the ring of balls translation and turning directly analogous to that of the ship. The display from the panel is scanned by a stationary television camera using reflection from the filter, to derive a bright plan-position picture in which only moving-objects have rearwardly-extending true-track 'tails,' and the ship itself always appears at the center. The table carrying the panel is reset to a central position periodically, the spring pressure on the balls being relieved and electrical energization of the panel interrupted to erase the historical record, at this time.
