摘　　要：论文介绍了一种基于LTC1562芯片设计实现多通道有源带通滤波器的方法。该设计应用于某主动声纳探测系统中,能有效去除带外噪声,减少杂波信号干扰,有效提高了信号拾取质量,同时多通道设计中,相位误差主要由滤波器引入,针对该问题进行设计,保证各通道信号的相位一致性。This paper introduces a method of designing and realizing multi-channel active bandpass filter based on LTC1562 chip.The design is applied to an active sonar detection system,which can effectively remove out-of-band noise,reduce clutter interference and improve the quality of signal pickup.In multi-channel design,phase error is mainly introduced by filters.The design aims at this problem to ensure the phase consistency of each channel signal.
