Abstract
The Ka-band SLAR which was developed by Shanghai Jiao Tong University had Carried out remote sensing files over the suburb countries of Shanghai where are agriculture areas. The authors have chosen some typical state farms and private farm fields as studying object. They summarized various factors to list a detailed table for interpretation of the SLAR imagery of city suburbs. The paper presents a simple and practical vegetation model with the Leaves Area Index (LAI). The paper also describs the vegetation classification and the analysis of land use by the interpretation of SLAR images.
Introduction
The JD-08 Ka-band side looking airborne radar (SLAR) developed by SJTU Marhc and May 1987. The flying regions are indicated by frames in
figure 1, including south bank of Chang Ming Island located at the mouth of Young-zi River (frame 1), Chang Xin Island and Heng Sha Island (Frame 2), the seacoast from Jin San Country to Fangxian Country of Hangzhou Bay (Frame 3 and 4). A group of clear SLAR pictures had beenacquired. We lay emphasis on pictures concerning frame 2 and 4. Our research purpose is to approach a general interpretation principle of radar remote sensing pictures over agriculture areas and to examine a vegetation scattering model with radar pictures, thus explaining the application prospect of SLAR images on agriculture.
