获得最小剩余度线性阵列的排列方法

Methods for Achieving Lingear Arrays with Minimum Redundancy

在分析线性阵列的最小剩余度理论的基础上，提出两种获得最小剩余度线性阵列的排列方法，使剩余度比其它的排列方法有很大改善，从而使阵列无线获得更高的分辨率．通过分析，总结出任意个阵元的最佳最小剩余度线性阵列的可能结构．根据两种具有不同用途的合成孔径微波辐射计的设计要求，对它们的天线阵列的阵元进行了最佳定位．

This paper presents two methods for achieving linear arrays withminimum redundancyfor any number of antenna element;All possible optilnum structures of such arrays with ele-ments less than 19 are given with the aid of a digital computer.The methods proposed haveimproved the minimum redundancy and shortened the computing time as can be seen from acomparison with other existing rnethods,thus enabling the linear array to reach a higher res-olution,In working out the optimum positioning of the elements in the antenna arrays fortwo synthetic aperture microwave radiometers fro different purposes,some problems in theactual application of Ishinguro' s recursive method are discussed.
