measuring distance radio frequency
Dear,
It is simple.You send a pulsed rf signal at Point A and receive it at Point B.with time
difference between send & receive you can calculate the distance.but your transmitter
controller & receiver processor must be synchronized.for example you can have
2 real time clocks,one @ A & another @B.in Tranmitter controller @ Point A you
can use a time table to send rf pulses,@ point B you know the transmitter time table
and when you receive rf pulse you can calculate the time difference and calculate
distance(by multiply time difference to light speed).but you must be careful,every
1us error in time gives you about 300meters error in distance.
Good Luck!
