Abstract
In this paper we presented a novel on-line adaptive recursive algorithm which is capable of resolving multiple coherent spatial sources, as is often the case in radar situation. Most of the adaptive beamforming algorithms fail to operate in such situation or their performance will be degraded. Our algorithm is based upon the travelling antenna concept introduced by Gabriel [1]. We test the performance of this algorithm using computer simulation. An eight-element array involving coherent sources of equal and unequal strength are used for the test. We compared the performance of this algorithm with the performance of the SMI algorithm. We find that this algorithm can successfully seperate two coherent sources.
