摘要
本文以声呐为例讨论了应用啾声(Chirp)信号于线阵的问题。文章研究了在接收机输入端混有噪声的条件下线性调频脉冲阵的波束形成的可能性。理论分析和计算机模拟表明,系统具有良好的距离分辨率、角度分辨率和高的信噪比增益。
Taking the sonar case for an example the application of a chirp signal for a linear array is described. In addition to the digitalized phase-correction technique, the array beamforming in the presence of noise is discussed. The theoretical analysis and computer simulation have shown that the system is characterized by the good range resolution and good angular resolution, as well as the high gain in signal-to-noise ratio.
