摘要

PS校准结合了外部设备，如角反射器、应答器和场景中的稳定目标，以提供对SAR仪器辐射质量的连续监测。目标是在图像块(例如10×10 km)的基础上提供精确的地理定位和辐射校准信息。本文研究了这类目标的选择能力、它们的固有稳定性以及ps辅助方法所能达到的性能。

Performances and limitations of Persistent Scatterers-based SAR calibration

The PS calibration combines external devices, like corner reflectors, transponders and the stable targets in the scene to provide continuous monitoring of the radiometric quality of a SAR instrument. The goal is to provide, on the bases of image blocks (say 10×10 km), the precise geolocation and the radiometric calibration information. The capability of selecting such targets, their intrinsic stability and the performances achievable by a PS-aided approach are investigated in this paper.
