本文给出了一种不仅能对消非相参干扰而且能对消相参干扰的新的自适应技术,它同时在观察方向保持固定的增益。这种技术由于应用了新的相关块阵和一个相减预处理器,因而不需要任阿空间平滑。在热噪声存在时,为了对消M-1个相参干扰机,它需要2M个阵列单元。在这种技术中应用的是这样一种矩阵,即在热噪声存在时,它能得到无偏估计值。这样,在寻求用于阵列天线的权矢量时,有助得到对噪声是鲁棒(robust)的算法。
This paper presents a new adaptive technique that can not only cancel non-coherent interference but also eliminate coherent interference, which maintains a constant gain in the viewing direction. This technique does not require any spatial smoothing due to the application of a new correlation block and a subtraction preprocessor. In the presence of thermal noise, it requires 2M array elements in order to eliminate M-1 coherent jammers. In this technique, a matrix is applied which yields an unbiased estimate in the presence of thermal noise. As such, when seeking weight vectors for array antennas, it helps to get algorithms that are robust to noise.
