摘要
从发掘相控阵天线潜力使其具有高精度、抗干扰和多功能等角度出发,对下列课题进行了研究:适当随机相位量化优化波束指向的算法;适当相位加权和振幅加权波瓣置零实数算法;适当相位加权和振幅加权的DBF实数算法;随机对角线加载算法对自适应算法的影响;新的线性调频信号检测和估计方法;非对称波瓣算法。以上算法均采用了适当改变技术(ACT)。计算机模拟结果证明,这些算法是行之有效的。
In this paper, appropriate change technique (ACT) is used in increasing accuracy of pattern beam pointing , adaptive digital beamforming (DBF), real phase-only (amplitude-only) nulling pattern synthesis, linear FM signal detection, diagonal loading and asymmetric pattern synthesis etc. Computer simulations are shown and results are in good agreement with theoretical analysis.
