The radar "looks" with the looking angle θ (or so called off-nadir angle). The angle α between x-axis and the line of sight (LOS) is called cone angle, the angle φ between the x-axis and the projection of the line of sight to the (x; y)-plane is called azimuth angle. Cone- and azimuth angle are related by cosα = cosφ ∙ cosε.
A pencil-beam radar A moving or sweeping pencil-beam radar. In optics, a pencil or pencil of rays, also known as a pencil beam or narrow beam, is a geometric construct (pencil of half-lines) used to describe a beam or portion of a beam of electromagnetic radiation or charged particles, typically in the form of a cone or cylinder.
The AN/APG-66 radar is an X-band [1] solid state medium range (up to 80 nautical miles (150 km; 92 mi)) pulse-Doppler planar array radar originally designed by the Westinghouse Electric Corporation (now Northrop Grumman) for use in early generations of the F-16 Fighting Falcon. Later F-16 variants use the AN/APG-68 or the AN/APG-83.
Radar engineering is the design of technical aspects pertaining to the components of a radar and their ability to detect the return energy from moving scatterers — determining an object's position or obstruction in the environment.
The AN/APG-68 radar is a long range (maximum detection range 80 kilometres [50 mi]) [2] Pulse-Doppler radar designed by Westinghouse (now Northrop Grumman) to replace AN/APG-66 radar in the General Dynamics F-16 Fighting Falcon. The AN/APG-68 radar is now currently being replaced on US Air Force F-16C/D Block 40/42 and 50/52 by the AN/APG-83 ...
Eglin AFB Site C-6 is a United States Space Force radar station which houses the AN/FPS-85 phased array radar, associated computer processing system(s), and radar control equipment designed and constructed for the U.S. Air Force by the Bendix Communications Division, Bendix Corporation.
This year’s an experimental new cone will look a little different. Here’s what it means. Colorful new hurricane cone of uncertainty is coming to forecast maps.
Scans at different angles by a weather radar. A weather radar sequentially surveys a series of vertical angles over 360 degrees in azimuth. The reflectivity at each of these angles represents the rate of precipitation along a cone that rises away from the radar. Every angle can be seen on a PPI image. However, this rate varies with altitude and ...
