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 ...

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 ...

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 ...

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 ...

Why is it snowing in your location, but nothing is showing up on radar? You might be experiencing issues from a weather radar ...

At a distance of 20 miles, the lowest the radar can see is about 1,000 feet off the ground. Travel 75 miles away, and the lowest the radar can see is about 6,000 feet off the grou ...

What's more, it does not emit radar beams that are reflected by an object and then deflected back to the receiver. Instead, it uses beams that are already present. Passive radar is not only cost ...
