摘要

提出了一种迭代时空傅里叶变换(STFT)方法，用于合成均匀间隔线性天线阵列的宽带可扫描频率不变方向图。该方法采用修改-投影迭代法对合成结果进行持续更新。通过合成具有均匀旁瓣电平(SLL)的可扫描FI图的实例，验证了所提方法的有效性和效率。

Efficient Scannable Frequency-invariant Pattern Synthesis Using Iterative Spatiotemporal Fourier Transform

An iterative spatiotemporal Fourier transform (STFT) method is proposed to synthesize a wideband scannable frequency-invariant (FI) pattern for a uniformly spaced linear antenna array. This method applies a modification-and-projection iteration to continuously update the synthesis results. An example for synthesizing a scannable FI pattern with uniform sidelobe level (SLL) is provided to verify the effectiveness and efficiency of the proposed method.
