1. A system for detecting obstacles on the ground onboard a carrier, comprising:

  • at least two continuous-wave radars, linked to a system for utilizing the detection data arising from the radars, each radar configured to perform localization of an obstacle;

    along a radial axis between the radar and the obstacle, by calculating the distance between the radar and the obstacle; and

    along a horizontal axis transverse with respect to a sighting axis of the radar, by calculating the azimuthal position of the obstacle; and

    wherein the system is configured to perform localization of an obstacle along a vertical axis by calculating the elevation of the obstacle using monopulse deviation measurement processing of data from the at least two continuous-wave radars.
