Web14 jan. 2024 · For example, 1dB more of output power in a Long Range Radar (LRR) will give us 2.8m to detect a bike, 6m for a motorbike and 11m for a typical car, as shown in Figure 4. When driving at high speed in a motorway, this can mean the difference between braking on time or crashing into an unexpected traffic obstacle. Figure 4. WebDetection range can be as low as 100 feet or less to over a mile. A radar may track a distant large vehicle instead of a closer small vehicle without any indication to the operator which vehicle the radar is tracking. The angle between the radar or lidar and target must be small for an accurate speed measurement.

WebThe minimum range at which radar can detect a target is controlled primarily by the length of the transmitted pulse. Some of the energy of the transmitted pulse leaks directly into the receiver, which overloads the receiver, causing it to be blocked or paralyzed. WebWe can use the following standard form of Radar range equation in order to calculate the maximum range of Radar for given specifications. RMax = [ PtGσAe (4π)2Smin]1 / 4 Substitute all the given parameters in above equation. RMax = [(250 × 103)(4000)(25)(4) (4π)2(10 − 12)]1 / 4 ⇒ RMax = 158KM
