Abstract (en)

[origin: WO9918451A1] The invention concerns a method for producing from passive sonar data operational images interactively controlled by the operator continuously according to operational requirements and compatible with information requirements in real time. The invention is characterised in that it uses a method for representing a multidimensional data field on a display screen (14) which consists in using the screen co-ordinates for two dimensions of data and three colour perception components among luminosity, hue and saturation for three other dimensions of said data, to produce bearing-time, azimuth-time, or frequency-time (circulating lofar) or frequency-bearing with representation of frequencies by hue or interactive filtering.
