Title: Linear-polarised orthogonal mode waveguide coupler having a coupling window of grating design
Inventor: ZOCHER EBERHARD DIPL ING
IPC: H01P1/165
Filed: 1993-09-13
Abstract: Orthogonal mode waveguide couplers, which have a waveguide junction in which a coupling window is located, are used to break down electromagnetic waveguide fields into components which are linear-polarised orthogonally. The feature of the new orthogonal mode coupler is coupling windows of grating designs by means of which considerably better characteristics are achieved (Figure). The invention relates to the coupling window with special polarisation-selective inserts. The example (Figure) shows a window having a plurality of thin webs which run parallel. Very good decoupling values, low forward losses and suitable matching values in conjunction with large relative bandwidths are achieved by optimisations relating to the number and thickness of the webs, the overall size of the window and its position in the waveguide junction. Linear-polarised orthogonal mode waveguide couplers of grating design are used where a number of frequencies are utilised, for example satellite television, communications, data transmission, telemetry, radar technology and for polarisation diversity operation. <IMAGE>

Title: Airborne SAR system for determining a terrain topography
Inventor: ZINK MANFRED
IPC: G01S13/935
Filed: 1993-09-24
Abstract: In the case of an airborne SAR system for determining a terrain topography, two complete, correlated SAR images, having different amplitude modulation in the range direction, are obtained and recorded by switching over between two antenna polar diagrams (which can be produced by means of a monopulse antenna), namely a sum polar diagram and a difference polar diagram. Desired terrain information is extracted from the amplitude ratio of the two SAR images. Furthermore, the terrain information can also be extracted from polarimetric SAR data via crosstalk parameters.
