use of RFID technology in soccerl.

[rama_ynwa]

i want to do a project in which rfid(active) is used to detect whether a soccer ball has crossed the goal-line or not.
i need help in building the transmitter and receiver circuits for the same.
i think they should be of high power as the whole soccer field is covered here.
thanks in advance

This is a big project for me. Nike and Adidas are doing some research on similar design. A positive or semi-positive tag was printed on footbal. But mechnical,size/weight is a big problem.
Not just one receiver installed, but a receiver matrix at several place. You might be able to find more information, if you get access to ieeexplore website. and search with "RFID, football".

i was just thinking if this is possible.
placing a receiver(s) near the goal post and a transmitter inside the ball.
Although i am not sure if such an IC is available in the market ,i will need an IC which can be used for transmitting purposes , since inside the ball , complicated circuits are to be avoided.
using RFID technology inside the ball along with the transmitter, we can detect whether the ball has crossed the line or not. i believe the detection is similar to the one used to prevent shoplifting.. i.e a person walks through a particular path (ball crossing the goal-line in this case)... and a signal can be transmitted from the ball to the receiver as soon as the ball crosses the line.. and i can flash an LED or something to show detection.
