摘要
本文介绍一种中心工作频率在45kHz，发射电功率8kw的16基元线列阵发射系统，并介绍了使用DSP56001数字信号处理器产生线性调频扫描被束发射信号及接收信号的频域处理和一些测试结果．
A 16 channel high power low frequency sonar transmitting system working ata frequency of about 4. 5 kHz has been developed. Each channal is driven by a 500 W lin-ear high power amplifier supplying to each element and the inputs to the amplifiers aredriven from a DSP56001 digital signal processor. This paper discribes the details of thesystem and the principle of its working linear FM scanning beam transmitting mode aswell as some measurements of its performance.
