About ultrasonic parking radar ranging, Based on piecewise nonlinear weight value Pso algorithm, There are cycle detection, periodic testing.

Lamb波的频散曲线是进行超声Lamb波无损检测的重要依据。本程序对Rayleigh2Lamb方程进行了分析，给出了无限大板中Lamb波频散曲线的数值计算方法，通过Matlab软件对求解过程进行编程，绘制出Lamb波在铝板中传播的相速度和群速度曲线，并通过试验进行了验证对推广应用Lamb波进行无损检测具有实际意义。(The dispersion curve of Lamb wave is an important basis for non-destructive testing of ultr

该程序在百科荣创的嵌入式开发平台实现超声波传感器测试功能，该车主控为STM32系列芯片(The program realizes the testing function of ultrasonic sensor on the embedded development platform of Encyclopedia Rongchuang. The main control unit is STM32 series chips.)

采用arduino连接超声波模块检测高度，输出到显示屏(Ultrasonic module testing highly connected by arduino output to the screen)
