摘　　要：一次相消技术是一种经典的固定点目标对消方法。本文讨论了在ISAR成像处理过程中利用一次相消技术来剔除地杂波,分析了在成像处理中的杂波相消方法,并在最后的计算机仿真中,验证了该方法的有效性,分别比较了两种成像方式、两种地杂波分布的成像结果。The first-order cancellation is one kind of classical idea for the purpose of canceling stationary target cancellation. In this paper the cancellation of the ground clutter in ISAR imaging by using the first-order cancellation is presented and the method of the clutter-canceling is also analyzed in detail. Finally, a computer simulation is given to illustrate the effectiveness of the proposed method. And it is compared that the imaging results with two kinds of imaging methods and under the condition of two kinds of ground clutter formats, respectively.
