Meaning of Scatterer and point scatterer as opposed to just using . . . A target can be composed of multiple scatterers Here, the two terms refer to two theoretically different things, but are obviously related since the scatterers compose the target The term "target" usually refers to an object of interest There can be many scatterers in the environment, but none of them is your "target"
Comparison between FMCW radar modulation techniques The low-pass filtered mixer output will then always be proportional to the range of the scatterers, regardless of a up or down sweep With a I Q receiver you should be able to distinguish between a negative and positive beat, but I can't see any benefit
How to calculate distances between stitching vias for RF lines? The lambda 10 rule of thumb is to provide a certain amount of attenuation at the frequency of interest I forget exactly what that attenuation level is, but if you need more attenuation you either space the vias closer together or you put in a second, staggered row of vias like the graphic shows
Does Ohms law always apply at any instantaneous point in time? If we measured instead across a time scale this small, we would observe small fluctuations around the Ohm's law voltage, due to the fact that the energy loss and gain of individual scatterers becomes resolvable in such short time scales
