Until recently phased array radar has been very expensive, used only for military applications where the cost of survival weighs in the balance. With the advent of low-cost microwave devices and ...
For this purpose, both TanDEM-X and TerraSAR-X use an active antenna consisting of an array of transmit-and-receive modules designed for rapid changes in the direction of the radar beam as well as ...
However, smaller wavelengths have the advantage of being able to be projected in sharper beams by smaller antennas and generally have higher precision (Bruderer 1997). Radar has several benefits ...
the radar image will not show echos from precipitation that lies outside the radar's beam, either because the precipitation is too high above the radar, or because it is so close to the Earth's ...
Prior to the move, the radar beam emanating from Slidell was typically scanning more than a mile above the ground in the Capital Region. At that elevation, it could be challenging for radar ...
