  • Patent number: 12170735
    Abstract: A chip device with a logic circuitry (105) protected by a randomized logic encryption based on a key (K) for preventing a designated usage of the logic circuitry (105) by an unauthorized user comprises: a physically unclonable function, PUF, (110), a storage (120), and a chip enabler (130) with one or more registers (132). The physically unclonable function, PUF, (110) is configured to generate a device-individual response (Re) based on a challenge (Ch). The storage (120) has stored the challenge (Ch) and a data element (C), the data element (C) being an encryption of the key (K) with the response (Re) of the PUF (110) as encryption key. The enabler (130) is configured to enable the logic circuitry (105) for the designated usage only, when the key (K) is transferred to the register(s) (132), the key (K) being a decryption of the data element (C) with the response (Re) as the encryption key.

  • Patent number: 11747460
    Abstract: An apparatus (100) for compensating for weather-independent Doppler expansions in radar signals of a weather radar system (200) is disclosed. The device comprises: a receiving device (110) for receiving a representation (50) of the radar signals, a calculation device (120) and a compensation device (130). The representation includes pixels of a range Doppler matrix. The calculation device (120) is designed to calculate azimuth angles (Azi) for the pixels (75) by means of fine bearing. The compensation device (130) is designed to correct weather-independent Doppler shifts for the pixels (75) based on the calculated azimuth angle (Azi; AziMopu) and thus to compensate for the weather-independent Doppler expansions and to provide them as a compensated representation (150).

  • Publication number: 20210270575
    Abstract: A missile warner includes a sensor, a recording device, and an evaluation unit. The sensor is configured to detect a potential missile. The recording device is configured to continuously store detector data generated by the sensor, for a predefined amount of time. The evaluation unit is configured: to recognize within the detector data, a detection signal of the potential missile, and to compare the detection signal with a declaration threshold value, and to generate, after the detection signal has exceeded the declaration threshold value, a warning signal of the potential missile, and to perform, upon the presence of the warning signal, a verification of the potential missile based on a temporal backtracking of the corresponding detection signal, wherein the backtracking includes an analysis of the stored detector data.

  • Patent number: 10605919
    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.

  • Patent number: 10444398
    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.
