Abstract: Apparatuses and methods for two-dimensional beam scanning for determining the position of an object in three-dimensional space are provided. An apparatus comprises a multiplicity of transmitters and receivers, which are arranged orthogonal to one another in an L-, U- or T-shaped structure. In one apparatus, the transmission signals are frequency and phase modulated in combination; and in another apparatus a single frequency carrier signal is subject to binary phase modulation. Here, this is a high-frequency encoding with a great code length, which is generated according to the pseudo-random number principle. The received signals, which include information from all transmitters, are decoded and consequently split into sub-signals, which can be assigned to a two-dimensional virtual array. According to the method of digital beamforming, the individual signals of the virtual antenna elements are formed into a plurality of highly focused beams in the horizontal and vertical direction.

Abstract: According to the invention, a device and a method are provided for determining the position of an object, in particular a moving object, in the three-dimensional space. The device comprises at least two switchable transmitting antennas having a different vertical position of the phase center as well as a plurality of receiving antennas which are arranged in series. The transmitting antennas are arranged in the horizontal direction and at a distance that corresponds to the distance of the receiving antennas. The transmitting antennas are vertically offset with respect to each other by a value that is less than or equal to half the free-space wavelength of the transmitted signal. The transmitting antennas can otherwise be arranged at any position around the receiving antenna. Horizontal beam sweep across a wide angular range is carried out according to the method of “digital beamforming”.

Abstract: The present radar altimeter operates in accordance with the frequency modulated continuous wave principle in the C-band. The altimeter is constructed with microminiaturized integrated circuits and provides a completely digital signal evaluation and mode control which enables the transmitter to produce a wave-form providing the altimeter with the following advantages. A silent mode during the signal evaluation greatly improves the resistance of the altimeter against electronic countermeasures. The transmitter frequency is stabilized and a compensation for Doppler frequency drift is provided. Further, the altimeter is able to discriminate between intended proper targets on the one hand and false or erroneous targets on the other hand. The altimeter is equipped with a self-testing unit which provides different functions in different modes.
