A generator of a frequency modulated radar signal includes a generator of a periodic signal frequency modulated over a part Tof a period T, corresponding to a square signal of which the frequency varies linearly in a first frequency band Bof central frequency f; an oscillator generating a sinusoidal signal of frequency f>fand included in a second frequency band B>Band corresponding to the linear variation of the frequency of the radar signal; and means coupled to an electrical supply input of the oscillator such that they generate a voltage for supplying the oscillator at the frequency of the frequency modulated periodic signal.

Generator of a frequency modulated radar signal

A transmit-array collimating assembly, this collimating assembly being able to convert a first electromagnetic wave radiated from a first focal point and in a first frequency band, into a plane electromagnetic wave of same frequency radiated in a preset first direction, and to convert a second electromagnetic wave radiated from a second focal point and in a second frequency band, into a plane electromagnetic wave of same frequency radiated in the same preset first direction, first and second primary radiating elements solely connected to first and second output ports of a transmitting module, respectively. The first and second primary radiating elements are positioned so as to radiate the first and second electromagnetic waves from the first and second focal points, respectively.
