System and method for ultrasound distance detection

摘要: A system for using ultrasound to detect distance on mobile platform and methods making same. The includes an transceiver that can transmit and/or receive waves determine from object of interest a time-of-flight the wave. is adapted reduce noise by dynamic model set constraints possible location received echo. linear, constant-speed be used constraints. further packetizing waveform filtering out according height width packets. likewise remove dead zones in subtracting aftershock waveform. systems are suitable detection any type platform, including unmanned aerial vehicles.
