Sadly, no. Unless you can convince the judge you are way too young for being the one who was speeding, and the officer padded your age to match the description of a suspect
On a serious note, you can and should try to fight the ticket. Here are a few pointers on how to fight a radar ticket. Please, feel free to ask for details (if you do, post as much info as possible from your ticket)
1) request discovery of all relevant records from DA's office (tipmra website has a good list), government must properly respond. Make sure you ask the court for continuance to allow ~40 days for records to arrive. Also send copy of discovery request to the court. Finally, add parallel FOIA request to PD for the same records. When records arrive, check the following:
2) do radar forks calibration and serial number match the ones used to test the radar?
3) was proper radar test done before and after shift?
4) did officer have FCC license and proper training (find out requirements)?
5) was the place formally checked for interference?
6) does the ticket say that traffic was heavy/medium?
7) was there a chance for sweep, ghost reading or other well-known radar errors (find them on trhe web)?
8) during trial, determine if the officer does have independent recollection of events (especially if the ticket has an error on it). This one requires a bit of research on how to do and how to object/motion for dismissal/stiking the evidence.
9) Is the speed limit properly posted and legal? (find MUTCD defense on the web)
If the answer is no to any of above questions, you have a case.
Also, make 2 copies of relevant caselaw (free parts of tipmra website have references, so you can find them on the web), and give them to judge and DA at the beginning of the trial. You will likely need to cite caselaw once you use above defenses.
And, the last but not least, make sure you make a copy of front and back of the ticket before sending it in, and also use certified mail to make sure it does not get lost.
Good luck.
