        "abstract": "This article describes the basic principles of radar remote sensing for scientific purposes. In addition, it provides several examples of the radar remote sensing instrument. Scientific remote sensing radar includes synthetic aperture radar (SAR), radar altimeter, scatterometer, meteorological radars, and radar sounder. A radar transmits an electromagnetic signal and receives a reflected echo from illuminated objects. From the received signal, useful information on the illuminated objects can be extracted for various applications. Examples of geophysical quantities that remote sensing radars can measure are land topography, surface deformation, biomass, soil moisture, ocean surface topography, ocean vector winds, cloud, precipitation, and subsurface layers. A radar is capable of collecting remote sensing data under almost all weather conditions, day or night.",

In this paper, the metrology system is described, and the performance is measured. The laser beam stability is discussed in detail. Pre-launch alignment and calibration are also described. The invisible infrared laser beams must be aligned to their corresponding detectors without deploying the telescope in Earth's gravity. Finally, a possible method for in-flight calibration of the metrology system is described.",
