Radar cross sections for mesospheric echoes at Jicamarca [PDF]
Annales Geophysicae, 2009 Radar cross sections (RCS) of mesospheric layers at 50 MHz observed at Jicamarca, Peru, range from 10−18 to 10−16 m−1, three orders of magnitudes smaller than cross sections reported for polar mesospheric winter echoes during solar ...

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022 Conventional airborne radar sounding techniques are well suited to the detection and characterization of flat-lying, specular subglacial water bodies. However, topographically positive, diffusively scattering Röthlisberger (R-) channels are more ...

Pitfalls in GPR Data Interpretation: False Reflectors Detected in Lunar Radar Cross Sections by Chang’e-3 [PDF]
IEEE Transactions on Geoscience and Remote Sensing, 2018 Chang’e-3 (CE-3) has been the first spacecraft to soft land on the moon since the Soviet Union’s Luna 24 in 1976. The spacecraft arrived at Mare Imbrium on December 14, 2013, and the same day, Yutu lunar rover separated from lander to start its ...

Terahertz radar cross section measurements [PDF]
35th International Conference on Infrared, Millimeter, and Terahertz Waves, 2010 We perform angle- and frequency-resolved radar cross section (RCS) measurements on objects at terahertz frequencies. Our RCS measurements are performed on a scale model aircraft of size 5-10 cm in polar and azimuthal configurations, and correspond closely to RCS measurements with conventional radar on full-size objects.
