Method and device for controlling a pulse generator for the emission of pulse signal of ultra wideband position-modulated type

摘要

Pulses of a signal, which are respectively contained in successive time windows, may be generated by a generator, and a control device may formulate a control signal for the generator including, for each pulse, an indication of its position in the corresponding window. The control device may include a processor to deliver for each time window, at a delivery frequency Fe greater than the pulse repetition frequency, successive groups of N bits together defining a digital cue of position of a pulse inside the window. Also, a converter may convert this digital position cue into the control signal temporally spread over the length (T) of the window and including the indication of position at an instant corresponding to the digital position cue. This makes it possible to position the pulse inside its window with a temporal precision equal to 1/N*Fe.
