A probing radar designed for simulation of radar echo of a meteorite within the ice sheet of the Antarctic Continent (III) (abstract)
We have succeeded in the simulation of a probing radar echo from meteorites within the ice sheet of the Antarctic Continent, and obtained the following. 1) On the region for the changing density profile, we did not obtain the probing radar echo from meteorites within the ice sheet. 2) As the probing...
