摘要
介绍了宽频带水下目标回波模拟技术的特点。采用DSP和PCI构建目标模拟器的数据采集处理系统、利用串并联谐振技术实现宽带阻抗匹配,配合大动态范围的模拟信号预处理机,研制了一种宽频带水下目标模拟器。目前该型目标模拟器已成功通过了试验,并由此证明其具有较好的宽带目标模拟功能。
The features of the target simulating technology of the underwater wideband signal are introduced. A type of underwater wideband target simulator is developed. DSP and PCI is chosen to comprise its data acquisition and processing system, serial-parallel resonant technology is used to achieve its wideband impendance matching network and an analog signal preprocessor with large dynamic range is designd. Now this target simulator is successfully applied on the test and its wideband target simulation function is well verified .
