Abstract :
Based on wave-front reconstruction theory, this paper analyzes the principle of improving azimuth resolution in spotlight mode by multiple SAR surveys, and the approach to implement it. Meanwhile, topographic effect on the approach is investigated. And the way to eliminate topographic effect is presented. The numerical simulation examples are given in the end to illustrate the results
