Taylor said that dark depression at Phaethon's center "could be a crater or some other topographic depression that did not reflect the radar beam
back to Earth.
When the radar beam
reaches a target, like a rain drop, it induces minute voltages and current in the target.
Steerability is necessary to keep the radar beam
trained on the sun, facilitating long observation times.
Furthermore, the product's radar beam
can be emitted over a wider angular range, without requiring a mechanism to adjust the angle, as with previous versions.
Radar detection is abstracted as a solution of the intersection between the geometrical representation of radar beam
and the targets.
As a radar beam
propagates away from the dish, it spreads out and moves upward in the atmosphere, like a flashlight beam tilted slightly upward and shining across a vast room.
Unlike conventional mechanical apertures that steer a radar beam
using motorized gimbals, Echodyne's MESA requires no moving parts to steer its beam.
Tenders are invited for Supply of Radar Beam

Measurements are substantially more reliable even in narrow tanks because the radar beam
avoids obstacles such as baffles on the tank walls, and is thus unhindered by interfering signals.
Combining the azimuth scanning capability of the AESA panel with that created by antenna rotation allows the radar beam
to dwell for a longer time on targets of interest, allows more rapid track formation, and allows a range of azimuth scan rates to be created from an array turning at a single speed.
Unlike conventional radar, however, the use of the building's own WiFi signal to illuminate the target means there is no incoming radar beam
that could alert the suspects to the surveillance.
When the satellite moves in the orbit, the radar beam
center line intersects with the Earth surface to form a group of points, known as targets.
