Modulation Pattern
The changing pattern in Frequency-Modulated Continuous-Wave (FMCW) Radar is the regular shift of a sent signal’s frequency over time. This changing is important to get useful details about the target, like its distance and speed. A often-used type of pattern is the sawtooth or triangle shape.
- Linear Frequency Change: The pattern of change in the transmitted signal is ongoing and follows a straight-line path. Usually, this shift happens in a shape that looks like the teeth of saw or triangle.
- Sweep Bandwidth: The variety of frequencies used in one full modulation round is called the sweep bandwidth. The more bandwidth a radar system has, the better it can tell where things are.
- Repetition Rate: It’s important to know how quickly the pattern is repeated in modulation for finding out how fast a radar system can be updated. More often updates can be made by doing this more frequently.
In this graph, the x-hub addresses time, and the y-hub addresses the recurrence of the communicated signal. The sawtooth design portrays the constant increment and ensuing reset of the recurrence. This example is central to FMCW Radar’s capacity to precisely quantify the reach and speed of targets.
