Recently, various algorithms for radar signal detection that rely heavily upon complicated processing and/or antenna architectures have been the subject of much interest. These techniques owe their genesis to several factors. One is revolutionary technological advances in high-speed signal processing hardware and digital array radar technology. Another

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]).

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 photographs of thunderstorms and the Florida hurricane of September 1945 were shown to illustrate structure of those storms (see Fig. 1). The relation between radar echoes and the reflecting material in the storms was discussed. Previous research has shown the intensity of the return radiation, among other things, to be proportional to the number

Radar Tomography For Cavities Detection
9th EEGS Symposium on the Application of Geophysics to Engineering and Environmental Problems, 1996Preliminary tests on laboratory models have enabled us to provide some guidelines for traveltime ray tomography with GPR applied to civil engineering problems, specifically to find voids in pillars, walls and structures. The width of the Fresnel zone and the source and receiver locations are the limits to resolution capability. For crosshole geometry a

RADAR DETECTION OF PRECIPITATiON
Journal of Meteorology, 1946Abstract 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.
