摘要

频率不变阵列广泛应用于通信系统、音频处理和雷达等领域。对于这种应用，需要带fir滤波器的宽带波束转向。提出了一种固定频率不变波束形成方法。该方法不需要最小化函数或傅里叶变换，可以实现波束控制。该方法是基于阵列频率特性的利用，并允许找到fir滤波器的真实系数。

Frequency-Invariant Beamforming with Real FIR-filters

Frequency-invariant arrays are widely used in communication systems, audio processing and radar. For this applications wideband beam steering with FIR-filters is required. The paper presents a fixed frequency-invariant beamforming method. Proposed method allows beam steering and it does not require minimizing functions or the Fourier transform. The proposed approach is based on the usage of frequency properties of arrays and allows finding real coefficients of FIR-filters.
