Study on wavelet denoise and characteristic extraction of echo signal to flaw classification in ultrasonic testing 超声检测缺陷分类的降噪及特征提取问题研究
Radar target simulator is used to generate radar echo signal comprised of target and radar environment 雷达目标模拟器是用于产生包含目标以及雷达环境信息的雷达回波信号。
Because the truths of the echo signal simulation are directly influenced by the accuracy of the simulation algorithms 模拟算法的优劣直接影响着模拟产生的回波信号的真实性。
This paper studies mainly on the cross - components in the underwater target echoes signal processing 本文以时频分析中的交叉项为主线,系统的研究了交叉项在水下目标回波信号处理中的应用。
This project will realize the sar echo signal simulation system , which is valuable in military and civil application 本课题基于硬件实现机载sar回波信号的模拟,具有较高的民用和军用价值。
