Abstract: A stimulation device notably for testing radio reception devices is provided. It includes a signal generator delivering an amplitude-phase law for beam-forming purposes, transmitted in the form of a composite laser beam which illuminates a matrix of photodiodes of an emission subassembly with active modules separate from the generator, each wavelength of the beam carrying one of the signals defining the amplitude-phase law, intended for an active module. The device comprises means for measuring the orientation of the composite laser beam relative to the matrix of photodiodes of the emission subassembly and the distance traveled by the beam thereto, and correcting the phase law generated by the signal generator so as to neutralize the stray phase-shifts induced by these parameters on the signals transmitted to the emission subassembly.

Abstract: Methods for locating electromagnetic pulse emission sources in an environment including reflectors is disclosed. In one aspect, the method includes receiving, by a detector, for each source to be located, at least one same emitted pulse, received directly from said source and received by reflection on one of the reflectors. The method also includes identifying direct subsets and reflected subsets, regrouping by pairs of direct subsets with reflected subsets, calculating, for each pair, differences in dates of arrival between the pulses of the reflected subset and the pulses of the direct subset of the pair, and determining the distance of each source from the detector from calculated differences in dates of arrival of the pulses of each pair.

Abstract: The invention relates to a method for testing the electromagnetic compatibility of a radar detector with at least one onboard pulse signal transmitter, wherein said radar detector and each onboard transmitter are part of the same platform, by means of eliminating the onboard component in the signals received by said radar detector, where the onboard component corresponds to the mix of the direct component and the reflected component onboard, said method comprising a training phase allowing the detected pulses to be divided into classes, grouping together the pulses for which at least two characteristics have a common range of values, and a phase of eliminating, the pulses that belong to the selected classes.

Abstract: The invention relates to a method for locating at least two sources emitting electromagnetic pulses in an environment comprising two reflectors.The method comprises receiving, by a detector, for each source to be located, at least one same emitted pulse, received directly from said source and received by reflection on one of the reflectors.The method further comprises: identification of the pulses received directly and the pulses received by reflection, grouping by pairs of pulses received directly with pulses received by reflection, calculating, for each pair, the difference between the date of arrival of the pulse received by reflection relative to the date of arrival of the pulse received directly, and determining the distance of each source from the detector from calculated differences in dates of arrival.

Abstract: The present invention relates to a method for locating sources emitting electromagnetic pulses, each source belonging to a carrier platform, the method comprising the following steps: receiving, by a detector, for each source to be located, at least one same emitted pulse, received directly and received by reflection on the carrier platform of another source, measuring the arrival direction, the arrival date and at least one invariant characteristic of each received pulse. The method further comprises the following steps: grouping together a first pair of pulses and a second pair of pulses, calculating the difference of dates of arrival between the pulses of each pair, determining the direction and the distance of each source from the detector from calculated differences of dates of arrival of the pulses of each pair.
