I am Abdallah Hammad, an electronics engineer, working as lecturer assistant
at faculty of engineering at shobra ( zagazig university ) Egypt.
I've finished my PSc since 1998 . I'm doing my MSc in the field of "ultrasonic ranging"
the title of my reseach is " an accurate ultrasonic range measurement system"
I 'm using the following techniques:
1- thershold method ( I make 2 cicuits :A- using simple components B- using
microcontroller Atmel 8951 )
2- curve fitting technique to improve the accuracy of distance measurement , i use also
microcontroller Atmel 8951 .
3- correlation method for optimal range measurement,using DAQs with a Pc.
I want you sir to support me with publications in the different other techniques used in accurate range measurement and other methods for measuring distance
also I want ultrasonic sensors high quality -long range at low cost do you know from where i get
