一、引言智能天线技术在20世纪60年代就开始发展，最初研究对象是雷达天线阵，目的是提高雷达的性能和电子对抗的能力。而其真正的发展是在20世纪90年代初，以微计算机和数字信号处理技术为基础，其发展也是从雷达开始的。到20世纪90年代中，在美国和中国开始考虑将智能天线技
I. INTRODUCTION The smart antenna technology started its development in the 1960s. The initial research object was the radar antenna array, with the purpose of improving the performance of radar and the ability of electronic countermeasures. Its real development was based on microcomputer and digital signal processing technology in the early 1990s and its development began with radar. By the mid-1990s, the United States and China began to consider smart antenna technology
