1. Waveform Comparison
The table describes the appropriate use and key characteristics of the three basic waveforms in radar systems.
It compares their capabilities in range, velocity, and angle detection, along with their structural features and typical applications.
| Waveform | Range | Velocity | Angle/Direction | Characteristics | Suitable Applications | |
|---|---|---|---|---|---|---|
| CW | ❌ | ✔️ | ❌ |
Very simple structure, Doppler-only |
Motion detection, Speed measurement |
|
| SAW | ✔️ | Limited |
✔️ requires ant. array |
Range-focused, Range-velocity coupling |
Static distance measurement, Level sensing, Simple object detection |
|
| TRI | ✔️ | ✔️ |
✔️ requires ant. array |
Separates range and velocity using up/down chirps, High performance |
Automotive radar, Tracking systems, Moving object analysis |
