稳健自适应任意阵列方向图综合方法研究

As the extensive application of array antenna in communication, radar and many other fields, the pattern synthesis technology becomes a basic research content in array signal process and has got great attention. Although a lot of various array pattern synthesis methods are proposed currently, which whether need large quantity of iterative process and heavy operation burden, or have the difficulty to choose the parameters of algorithms or only aim at the special array configuration and lack the ability to others, namely lack the generality.. Especially important, in the above mentioned approachs there exist all kinds of array errors, which have got bad influence on the pattern synthesis effect. Therefore, in order to resolve the series of problems as above mentioned, this project will be based on pattern synthesis of array antenna as the main researching content and will put the robust adaptive arbitrary array pattern synthesis as the key research. The new approach that proposed in this project will further improve the fault tolerance, adaptability and accessibility of the arbitrary array pattern synthesis technology.. In this project, as an innovation, a new way is put forward to research the robust adaptive arbitrary array pattern synthesis on the basis of the existing pattern synthesis methods. And it has been proved valid through the theory analysis and simulation examples. It will provide new ideas and methods to research array antenna pattern synthesis technology and provides strong technology support to apply the array antenna pattern synthesis technology. This study has not only strong application background, but also great researching value, they not only can great promote the development of the adaptive array pattern synthesis technology, but also can go on further fundamental theory research in the robust adaptive array signal process field..

随着阵列天线在通信、雷达等众多领域的广泛应用，方向图综合成为阵列信号处理的一项基础研究内容，且受到了广泛关注。尽管当前提出了各种任意阵列方向图综合方法，然而不是迭代过程运算量大，就是算法中参数的选择比较困难，或着只是针对某些特殊的阵列配置，缺少通用性。尤其重要的是，由于各种阵列误差的存在，严重影响方向图的综合效果。因此，本项目拟将阵列天线的方向图综合作为研究内容，重点开展针对任意阵列的稳健自适应方向图综合方法，进一步提高方向图综合方法的容错性、适应性和易用性。本项目创新性地提出了研究稳健自适应任意阵列方向图综合方法，为阵列方向图综合技术研究提供了新的思路和方法，也为阵列方向图综合方法的应用提供了强有力的技术支撑。本项目的研究不仅具有较强的应用背景，而且具有较强的研究价值，其不仅可以极大地推动和促进自适应阵列方向图综合方法的发展，同时也可在稳健自适应阵列信号处理等领域进行深入的基础研究。
