yes this is triangular measurment technics. my project will be phase differences measurment between transmitted and received signal. yes measurement is nonasecond level.
i know it is hard but this is project and i confuse some implementing theory for example oscillator design which should be stable. thats why i m asking you whose experinces better than mine. just i need some hint and tips to do easy. it will be also test and keep try different ideas due to this is the project
thank you
