Abstract
The Space-Time Adaptive Processing (STAP) algorithm that is well-known in area of multi-channel airborne radar requires very high computing power and hardly implements. In this paper, detail analysis of computation steps of partially-adaptive STAP algorithm is presents, which indicates that there is a natural, inherent parallelism in STAP algorithm. A parallel algorithm based on multi-DSP system of partially-adaptive STAP is presented. The execution model, task mapping strategy and performance evaluation functions of this algorithm, is also illustrated. Data remapping is used between successive computation steps of STAP. The effectiveness of the implementation is demonstrated with experimental results.
