摘要： The present invention relates to a radiometric imaging device and a corresponding method for scanning a scene. The proposed device comprises a radiometer configured to detect radiation in a predetermined spectral range emitted from said scene and to generate a radiation signal from said detected radiation, and a processor configured to process said generated radiation signal by de-convoluting said generated radiation signal by use of a distance-dependent de-blur kernel, which is determined depending on the distance between said scene and the radiometer. This effect is dominant in the non-reactive near-field of the antenna. Due to the distance-dependent de-convolution a significantly improved image quality can be achieved.
