| Popis: |
In order to verify the imaging effect of long synthetic aperture time imaging, we describe an airship-born SAR experiment firstly and present measurement results. In May 2019, a measurement campaign was conducted in Jiangsu Province in China. In this paper, the equipment composition is described. Imaging results show that the two-dimensional spectrum of echo signal based on stationary phase principle is no longer valid because of the azimuth wavenumber is larger than the range wavenumber. Therefore, the frequency domain imaging algorithm is difficult to apply in the raw data processing. So the BP imaging algorithm is used to process experimental data. |
