摘要
提出了一种采用拉伸处理和相位补偿技术的宽带宽角接收波束形成新方法,给出了实现示意框图。与基本的时域和频域处理方法相比,新方法计算简单,所需设备量少,并能有效降低接收信号的带宽,易于工程实现。计算机仿真结果表明新方法是可行的。
A novel received beam forming method based on stretch processing and phase compensation in the presence of wideband signal and large scanning angle is presented, and the realization chart is given. Compared with the basic processing methods in time domain and frequency domain, the new approach is simple computationally and demands fewer equipment. Moreover, it can reduce the bandwidth of the received signal, and is easily implemented in practical engineering. Computer simulation result demonstrates the effectiveness of the proposed method.
