Abstract:

在输电线路无源干扰研究中,经常需进行宽频带的线路散射场扫频计算,而当前各类算法每次只能计算单个频点,现有计算机硬件条件无法解决短波及以上宽频带计算问题。针对该问题,提出了利用矩量法求得若干采样点的散射场信息,将基于模型的参数估计技术应用于类似于输电线路的电大尺寸散射体频率响应内插求解的思想。以IEEE研究频段和调幅广播收音台站工作频段为例,分别建立输电线路无源干扰直线模型和线-面混合模型,结合矩量法求解出等间隔采样点的散射场,选择Padé有理函数对各频带的散射场进行插值,从而快速预测出输电线路散射场的频率响应近似值。研究表明,MBPE技术插值精度与采样点数量、位置有关,若采样点选择恰当,其全局极值最大相对偏差可不超过4%。
