| Popis: | A method for construction of a 2D radio image of an asteroid from the radar data obtained with the use of a continuous monochromatic signal has been tested. The method is based on the inverse focused synthesis of the antenna aperture due to the rotational motion of the object and reconstructive computeraided tomography. On the basis of the analysis of the echo signals from asteroid Golevka, a 2D distribution of its surface radio brightness has been constructed. Reconstruction of the asteroid silhouette confirmed that Golevka has a not very elongated angular body whose maximum diameter is 620 m and the minimum diameter is 460 m. |
