摘要
Abstract
Frequency focus matrix based on least square method was brought forward. First, directional vectors were constructed for every frequency of the wide-band signal at all possible direction. Then, the directional vectors were constructed for the focus frequency at all the directions. Finally, the least square method was applied to get the focus matrix according to the directional vectors. This method avoided pre-estimation of the DOA of the wide-band signal, and was of high stability and angle resolution. Computer simulation was made to test it finally, and the result was correct.关键词
