【摘要】：對于SAR主影像(master)和從影像(slave)的幾何配準(zhǔn),文中采用三次基本多項(xiàng)式與斜距-多普勒定位模型,解算出主影像中心像素點(diǎn)在從影像中的同名點(diǎn),最后得出主從影像中心像素點(diǎn)的初級(jí)配準(zhǔn)偏移量。本文以上海地區(qū)ERS-1影像數(shù)據(jù)為例,在Matlab環(huán)境下,對SAR主從影像的幾何配準(zhǔn)偏移量進(jìn)行解算。實(shí)驗(yàn)結(jié)果表明,采用文中初級(jí)配準(zhǔn)方法,初級(jí)配準(zhǔn)相對精度可達(dá)到0.1%~0.9%。
[Abstract]:For the geometric registration of SAR main image (master) and slave image (slave), the cubic fundamental polynomial and oblique range-Doppler localization model are used to solve the homonym point of the central pixel of the main image in the slave image. Finally, the primary registration offset of the central pixel of the master-slave image is obtained. Taking the ERS-1 image data of Shanghai area as an example, the geometric registration offset of SAR master-slave image is calculated under the Matlab environment. The experimental results show that the relative accuracy of primary registration can reach 0.1% by using the primary registration method in this paper.
