In the short range slowly moving target detection of airborne fire-control radar, the space-time trajectory of clutter varies with range due to the variation of elevation angle and show high non-homogeneity. In such cases, good detection performance can not be obtained by using either conventional or STAP processing. In this paper, a compensating method of clutter trajectory is proposed. Transforming data of different range with different frequency-shift, it can weaken the non-homogeneity effectively and make the clutter energy shrink to a very small area in the space-time plane. The computer simulation results show good performance and high improvement factor can be obtained when it is used as the pre-processor of STAP and it has the advantages of low complexity and ease of application
