Abrégé
The present disclosure relates to a method for computer-implemented processing of SAR raw data, which comprises radar echoes from radar pulse. An interference radar echo and an interference pulse are associated with a respective radar pulse, wherein the interference pulse and the respective radar pulse have orthogonal waveforms. SAR raw data are focused by a first focusing on the interference pulses including a range compression and an azimuth compression, to obtain first focused data, where a filtering is used for the range compression of a respective radar pulse, which filtering is matched to the waveform of the associated interference pulse. Thereafter, the first focused data undergo a signal suppression, which at least partially suppresses the interference radar echo, as a result of which second focused data are obtained. These second focused data finally undergo a defocusing including range decompression and azimuth decompression to obtain modified SAR raw data.

The invention relates to a method for determining the power control parameters in order to control the power, in particular the energy per symbol, with which signals are transmitted from transmitters of a group of multiple transmitters to a receiver assigned to said group in packets according to a multiplex specification in a communication system. Each transmitter of a group determines the transmitter transmission power randomly such that the signal-to-noise ratio of the receiver lies between a minimum and a maximum value. The minimum and maximum signal-to-noise ratio values that determine to which group a transmitter belongs are defined in a first table, and the probability value used for the transmitter is defined in a second table in order to determine the transmission power of the transmitter such that the transmitter signal-to-noise ratio lies within the total range of permissible signal-to-noise ratios or within the signal-to-noise ratio that is permissible for the group to which the transmitter belongs. New values for the first and second tables are defined such that the maximum load in packets per seconds which can be accepted by the communication channel while maintaining a desired threshold packet error rate is maximized and/or the distance from the histogram of received signal-to-noise ratios in dB to a uniform histogram of signal-to-noise ratios in dB is minimized.

In a movement system, the movement limit is determined by having a degree of freedom of the movement system defined and the respective current movement system state being available. Subsequently, an articulation trajectory is determined for each upper articulation point of the movement system, on which articulation trajectory the articulation point can move along the degree of freedom. The movement limit is then derived by calculating the point of intersection of the actuator movement in an extreme deflection with its respective articulation trajectory.

The method for providing a warning of radiation-dose-relevant space-weather events at cruising altitudes comprises the steps of detecting radiation data of the atmospheric radiation, particularly ionizing radiation in the atmosphere, and providing a radiation model for 3D-spatially resolved estimation of a radiation field at cruising altitudes of the earth's atmosphere by use of a radiation dose rate scale based on a continuous range of values. Moreover, the 3D-spatially resolved rates of the effective radiation dose on the basis of the detected radiation data and the radiation model will be estimated. The radiation dose rate scale is divided, based on a continuous range of values, into a discrete, i.e. graduated radiation dose rate scale comprising individual successive ranges of values of increasing radiation dose rates, and respectively one index will be assigned to each range of values, wherein a first range of values is between a radiation dose rate of zero and a presettable first upper limit, a second range of values is between the first upper limit and a second upper limit which is equal to a presettable multiple of the first upper limit, and each further range of values is between the upper limit of the next smaller range of values and an upper limit which is equal to the presettable multiple of the upper limit of the next smaller range of values. As a warning, there is indicated the index of that range of values within which is situated the estimated radiation dose rate for a presettable range in the earth's atmosphere.

A reflector antenna for synthetic aperture radar, having a reflector including a reflector surface, a vertex, and an optical axis. The reflector antenna also as a plurality of antenna elements arranged side by side and in a row, for transmitting radar transmission signals and receiving radar reception signals produced from a reflection on a surface. The reflector is designed as a one-dimensional defocused reflector having two focal planes. The optical axis coincides with the line of inter-section of two imaginary planes extending at right angles to one another. The reflector has, in a first (X-) plane, a first (X-) focal plane that extends at right angles thereto and to the optical axis, and, in a second (Y-) plane, a second (Y-) focal plane which extends at right angles thereto and to the optical axis. The second (Y-) focal plane is at a greater distance from the vertex than the first (X-) focal plane.

Inventeur(s)
Vajen, Hans-Hermann
Abrégé
The processing of remote sensing data, wherein first image data are processed with the use of second digital image data which, compared with the first image data, have a finer local resolution. The local resolution of the first digital image data is refined temporarily. The local resolution and every pixel of the temporarily refined first image data corresponds to the local resolution and each pixel of the second digital image data. Determining a weighting value for the pixels of the second digital image data which corresponds to a weighting of a image value of the pixel in the ratio of the image value of the pixel to image values of surrounding pixels. A smoothing of the local plot of the image values in the area of the pixel and its environment is implemented such that the weighting value of larger values is based on additional smoothing of image values.
