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 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.

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.
