摘要
根据实际需要,研究了一种基于GSL(GNU scientific library)的吊放声纳信号处理实现方法,该方法以通用CPU(central processing unit)作为平台,Visual Studio作为软件开发工具,对GSL的数学运算函数进行二次封装,充分利用编译环境强大的调试功能,降低调试难度,从而减少开发人员工作量,缩短开发周期。文章简单介绍了吊放声纳信号处理算法的原理,并在此基础上着重介绍了GSL的设计思路和实现方法,最后进行实验验证,模拟目标回波信号作为输入数据,信号处理结果验证了该方法的正确性和有效性。
According to the actual needs,the paper studies a method to process the dipping sonar signal based on GNU,which uses general CPU(Central Processing Unit)as platform and Visual Studio as software development tool to encapsulate GSL's mathematical operation function,make full use of the powerful debugging function of the compilation environment,reduce the difficulty of debugging,thus reduce the workload of developers,shorten the development cycle.The paper briefly introduces the principle of dipping sonar signal processing algorithm,and on this basis,focuses on the design ideas and implementation methods of GSL,and finally performs experimental verification,simulating the target echo signal as input data,and the signal processing results verify the correctness and effectiveness of the method.
