Radar Detection of Iapetus

Science, 2004
Saturn's satellite Iapetus has the largest albedo asymmetry of any natural satellite, with the optical albedo of its trailing hemisphere as much as 10 times that of its leading hemisphere ([ 1 ][1]).

Introduction to Radar Detection

2015
Radar systems are faced with the problem of discriminating the useful target echoes from the interference background, which hides the target making its detection difficult. Thus, the taskof a radar processor is to decide whether or not the collected returns contain useful signal components. This problem can be formulated in terms of a binary hypothesis

Radar Detection of Phobos

Science, 1989
Radar echoes from the martian satellite Phobos provide information about that object's surface properties at scales near the 3.5-cm observing wavelength. Phobos appears less rough than the moon at centimeter-to-decimeter scales. The uppermost few decimeters of the satellite's regolith have a mean bulk density within 20% of 2.0 g cm

RADAR DETECTION OF PRECIPITATiON

Journal of Meteorology, 1946
Abstract Detection of precipitation by radar is possible because of the scattering of high-frequency radio waves by precipitation forms. Radar echoes being thus directly related to precipitation may be classified in a simple manner according to meteorological origin.
