摆扫式（whisk broom）和推扫式（push broom）卫星传感器介 …
2024年3月26日 · 目前，我们卫星传感器主要有两大类型：摆扫式（whisk broom）和推扫式（push broom）。 为了更好的理解和使用卫星影像数据，我们需要简单了解下这两种传感器工作原理。
NASA SVS | Landsat sensors: pushbroom vs whiskbroom
2017年10月31日 · In contrast, the instruments on Landsat 8 view across the entire swath at once, building strips of data like a pushbroom. This approach requires no moving parts and gives the sensor detectors greater dwell time.
Difference between Whiskbroom Sensor vs Pushbroom Sensor
Whiskbroom Sensor. The figure-1 depicts Whiskbroom Sensor which uses linear or area array of detectors. Here image is built up by movement of satellite along its orbital track and by cross-track scanning using a mirror. Example: LANDSAT MSS/TM Cross-track scanner uses "back and forth" motion of the fore-optics.
Push Broom and Whisk Broom Sensors - NV5 Geospatial
2013年9月24日 · A push broom scanner receives a stronger signal than a whisk broom scanner because it looks at each pixel area for longer. One drawback of push broom sensors is that the detectors in the "push broom" can have varying sensitivity. If they are not perfectly calibrated, this can result in stripes in the data. Figure 2.

2016年6月3日 · 目前，我们卫星传感器主要有两大类型：摆扫式（whisk broom）和推扫式（push broom）。 为了更好的理解和使用卫星影像数据，我们需要简单了解下这两种传感器工作原理。
CASA0023 Learning Diary - 3 Remote Sensing Data
There are two ways in which satellites collect remotely sensed data. Table 3.1: Table contrasting whisk and push broom methods. Image Sources: Shippert ( n.d.) A continuous line, covering a large swath over a large study area. Taking multiple passes over a more localised study area. Efficient over a large scale, covering a wide area in one go.
Geostationary / geosynchronous : 36,000 km above the equator, stays vertically above the same spot, rotates with earth - weather images, e.g. GOES (Geostat. Operational Env. Satellite) Geostationary satellites capture a (rectangular) scene, sun-synchronous satellites capture a continuous swath, ... which is broken into rectangular scenes. 2.
What is Sensor Scanner - Whiskbroom & Pushbroom Scanner
Sensors that use the pushbroom scanning include; SPOT, IRS, QuickBird, OrbView, and IKONOS. Pushbroom vs Whiskbroom Scanner. A push broom scanner receives a stronger signal than a whisk broom scanner, because it looks at each pixel area for longer. One drawback of push broom sensors is that the detectors in the push broom can have varying ...
