摘要

提出了一种应用于无线电监视的非均匀阵列天线扩展数字波束形成技术。我们尝试结合扩展(和与差)共阵的概念来提高阵列自由度(DOF)，这样我们就可以用更窄的主波束和更多的空数来创建更好的波束方向图。通过数字波束形成的计算机模拟，评估了所提出的阵列配置的性能。我们还研究了适用于扩展阵列的调制/解调方法。

Extended beamforming by sum and difference composite co-array for radio surveillance

This paper presents a way of extended digital beamforming technique by non-uniform array antenna used for radio surveillance. We try to enhance the array degree of freedom (DOF) by combining the concepts of extended (sum and difference) co-arrays, so that we can create a better beampattern with narrower mainbeam and more number of nulls. Performance of the proposed array configuration is evaluated through computer simulation of digital beamforming. We also study the way of modulation/demodulation which is effective for the extended arrays.
