Maximum Range and Range Resolution
The following terms are discussed below in detail:
Maximum Range
Maximum Range means the longest distance radar can find a target and measure how far away it is. Figuring out how far the signal can go depends on things like, strength of sent message, ability to hear it at other side and what pattern is used.
Factors affecting Maximum Range:
- Transmitted Signal Power: Using more power lets the radar signal to go farther and still come back with a sign we can find.
- Antenna Gain: An antenna with more gain sends energy very strongly and makes the received signal better, increasing how far it can go.
- Sensitivity of Receiver: A better listener can find weaker bouncing signals, letting us see targets from further away.
Range Resolution
Radar resolution is how well a radar system can tell apart nearby targets in the side-to-side direction. It’s affected by how wide the signal we send is and it’s very important for jobs that need to separate close things.
Factors affecting Range Resolution:
- Sweep Bandwidth: Having a bigger range lets us tell the difference between targets that are close to each other better. The more bandwidth, the better your range resolution gets.
- Signal Processing Techniques: Better signal processing tools can make things clearer by getting more details from the signals we get.
