The #1 Most Critical Factor in High-End Radar & Communications Systems: Low Phase Noise
If you’re anyone involved with the design and implementation of communication systems, you most likely hear that word “phase noise” all the time. Maybe even more times than you’d like. Get used to it for now, it will be used a lot in this post.
There’s a good reason for all this phase noise chat. It’s one of the key factors that determines the overall success or failure of your radar or communications application. It’s even more of an importance in intense environments where strong vibration or g-force is a concern.
So the question is, why is maintaining low phase noise such a concern in these applications and environments? And of course, that question wouldn’t be worth asking unless we also answered how to solve any problems associated with the effects of phase noise. You will know how and why you should decrease phase noise in applications by the end of this article.
One of the most significant changes to the way the military operates has been the integration of GPS for positioning, navigation, and timing purposes, which has given military forces unprecedented command and control over battle grounds. Troops and command centers are now in a state of continuous situational awareness, with an endless stream of data being added to military servers at all time.
