In this thread I am going to make some comments related to problems with countermeasure testing that appear here. A few other folks on this board have posted on these issues and I hope they will contribute. The purpose of this thread is not to criticize but to educate. I hope that comments here will be considered for the Guys of Lidar (GOL) II tests coming up. At the end of the thread I think we should try to come up with a consensus protocol for the guys to follow.
