摘　　要：针对目前舰艇声纳检测维修中无法进行换能器动态参数测量的实际,利用TMS3205509A和ARM7TDMI CPU设计了一种便携式声纳换能器动态参数检测仪。利用ARM7控制信号源生成不同频率的扫频信号激励换能器,通过高速A/D采集信号经预处理后送入TMS3205509A进行DFT处理,之后通过计算得到换能器动态参数。与现有的实验室大型测试设备相比,该仪器集信号产生、检测和计算于一体,携带方便、测试简单,测量精度完全满足随舰测量指标要求。In order to solve the problems that the shipboard sonar transducer dynamic parameter cannot be measured in maintenance support, a portable detector of sonar transducer dynamic parameters is designed by using of TMS3205509A and ARM7TDMI CPU. Signal source is controlled by ARM7 and different frequency sweep signal is generated. The DFT calcu-lation is done by TMS3205509A after high-speed A/D acquisition signal. Then the transducer dynamic parameters is obtained by calculation Compared with the existing laboratory large-scale test equipment, the detector has the advantages of portability and usability, and the measuring accuracy completely satisfy with the requirement.
