The future operational scope of seeker heads for surface to air and air to air applications require highest precision in order to achieve direct hits, while ECM resistance and high agility in terms of beam steering must be realised simultaneously. These requirements can be met using a Ka-band radar seeker with an electronically steered antenna. Such an electronically directed antenna beam also give...
In many scientific research domains and in all areas of industrial application the current trend is to develop efficient "intelligent" systems by shifting more and more effort to the digital computation level. To assure the data transmission between the processing unit and the executing mechanical modules (i.e. car braking systems), the development of new actors and sensors allowing the...
The growing demand of automatic process supervision in various areas requires the development of new sensors. However, for most applications only single function sensors have been developed. For technical reasons (space, computation power) on the one hand and economical reasons (cost) on the other hand, a limit in the amount of parameters to be controlled will be reached soon and further improvement...
This paper presents a new system implementation of an active antenna for a forward looking airborne SAR with digital beamforming on-receive-only. 56 receiving antennas are used together with one transmit antenna where each antenna illuminates the whole covered swath. A simplified hardware configuration is achieved by switching through the receiving array, thus sequentially recording return signals...
Following the demands of modern society for more mobility and more information, future generation base stations have to provide more data transmission capacity requiring a flexible management of the resources code, time, bandwidth and space. The air interface and hence the antenna is of significance for bandwidth and space, because the RF-performance of the antenna limits the performance of any used...
