Individual neutrinos received at Gran Sasso could have come from protons early or late in the proton pulse, creating uncertainty in their exact travel time, detractors said.
Comparing with the differential range method that early radar adoptive for measuring velocity, the radar, which based on Pulse-Doppler theory, has the better real time capability and high precision.
与早期雷达采用距离微分方法测速相比，基于脉冲多普勒理论的雷达测速技术具有实时性好、精度高等优点。

The best results will be achieved with early involvement in a handset project, in which Pulse has a lot of experience.
