Abstract: A method for processing echo pulses of an active 3D sensor to provide distance measurements of surroundings in front of the active 3D sensor includes defining a near range distance from the active 3D sensor and defining a last echo distance from the active 3D sensor greater than said defined near range distance. The method includes receiving a sequence of echo pulses of a signal emitted by the active 3D sensor and subjecting the sequence of echo pulses to a pre-defined trigger condition such that only those echo pulses are taken into consideration which fulfill the predefined trigger condition. The method also includes determining, from the echo pulses which fulfill the predefined trigger condition and that are received from distances greater than a defined near range distance, a first echo pulse and an adaptive echo pulse, and providing distance measurements of the surroundings in front of the 3D sensor using the determined first echo pulse and the determined adaptive echo pulse.

The system also includes an optical jammer configured to provide at least one jamming signal, and a directing device configured to direct the jamming signal towards the position in response to the output warning in order to prevent target acquisition or at least to make target acquisition more difficult.

Abstract: A method of processing 3D sensor data to provide terrain segmentation involves processing the 3D data so as to analyze the positions of sets returns from the terrain in the horizontal plane. Returns from an idealized flat terrain form a series of scanlines in the horizontal plane. A return having a significant displacement in the horizontal plane in comparison to other returns in the same scan line is classified as a non-ground return corresponding to an elevated object.

Abstract: A method for assessing a ground area for suitability as a landing zone or taxi area for aircraft is provided. Three-dimensional data for the ground area in a plurality of measurement cycles in a 3D sensor is produced. The measured-value density of the three-dimensional data and also of at least one further statistical property of the three-dimensional data is determined. A measure of the local roughness of the ground area is produced based on the measured-value density and the at least one further statistical property. The individual area elements of the ground area are classified on the basis of the roughness values produced according to the degree of suitability of said area elements as a landing area or taxi area.
