双曲结构VFDF雷达干扰宽带多波束形成技术

Broadband Multi-beam Forming Technology of Hyperbolic Structure VFDF Radar Jamming

采用一种高效的双曲结构可变分数延时滤波器(VFDF)实现了宽带波束形成,可以在不改变滤波器系数的情况下改变波束指向,并采用这种可变分数延时滤波器实现了雷达干扰宽带多波束形成,通过共用子滤波器减小了硬件开销。

This paper uses a variable fractional delay filter （VFDF） with efficient hyperbolic structure to achieve broadband beam forming, which can change beam direction without changing filter coefficients,and realizes broadband multi-beam forming of radar jamming with the VFDF, reduces hardware cost by sharing sub-filters.
