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。
In this paper, the sonar is used as an example to discuss the problem of applying the chirp signal to the linear array. The article investigates the possibility of beamforming of a chirp burst at the receiver input with noise. Theoretical analysis and computer simulation show that the system has good distance resolution, angular resolution and high SNR gain.
