摘要： Process and system for the location of emitters in the radar frequency range on the basis of cross position-finding by at least two flying platforms with, in each case, at least one passive HF sensor for ascertaining the geometrical and electronic properties of the emitter beams, whereby the flying platforms mutually exchange data for describing the geometrical and electronic properties of the emitter beams, and whereby from the plurality of the position-finding beams' possible intersection points, which arise from the emitter surveying operation, use is made, in order to determine the emitter position, of those intersection points at which the electronic properties of the intersecting emitter beams are identical.

摘要： A method for effecting the airborne determination of geographic coordinates of corresponding pixels from digital synthetic aperture radar images, where the SAR images are available in the form of slant range images and the recording position of the respective SAR image is known. The coordinates of the corresponding pixels in the SAR images and the corresponding range gates are used in each case to determine the distance between a corresponding resolution cell on the ground and the respective recording position of the respective SAR image. The determined distances and associated recording positions of the SAR images are used to determine the geographic coordinates of the corresponding pixels in the SAR images by employing a WGS84 ellipsoid.

摘要翻译： 从数字合成孔径雷达图像中实现对相应像素的地理坐标的空中确定的方法，其中SAR图像以倾斜范围图像和相应SAR图像的记录位置的形式可用。 在每种情况下，使用SAR图像中的相应像素和对应的范围门的坐标来确定地面上相应的分辨率单元与各个SAR图像的相应记录位置之间的距离。 SAR图像的确定距离和相关记录位置用于通过采用WGS84椭球来确定SAR图像中对应像素的地理坐标。
