Range profiling of the rain rate by an airborne weather radar

Remote Sensing of Environment, 1990
A class of methods based on a measure of path attenuation that is used to constrain the Hitschfeld-Bordan solution is investigated. Such methods are investigated for lidar, radar, and combined radar-radiometer applications. Their function is to allocate the attenuation in proportion to the strength of the measured reflectivity.

Clutter Suppression for Airborne Weather Radar Using 3D-STAP

2020 IEEE 5th International Conference on Signal and Image Processing (ICSIP), 2020
For airborne weather radar, a major task is to detect the echo signal of meteorological targets among severe ground clutter. It is well known that traditional two-dimensional (2D) space-time adaptive processing (STAP) is an advanced technique to detect moving objects under background of ground clutter.

Improved Retrieval of Reflectivity Factor for Airborne Weather Radar

Advanced Materials Research, 2014
For the airborne weather radar signal processing, the intensity of the meteorological targets is represented by the physical quantity called reflectivity factor. When observing the middle-or long-range meteorological targets at low altitude from a high-altitude radar platform, due to the incomplete beam filling, the retrieval result of the reflectivity

APAR: The Next Generation of Airborne Polarimetric Doppler Weather Radar

2021
<p>A novel, airborne phased array radar (APAR) is currently under design at the NCAR Earth Observing Laboratory. This novel airborne radar is to be carried by the NSF/NCAR C-130 aircraft. The APAR system will consist of four removable C-band active electronically scanned arrays (AESA), strategically placed on the fuselage of the aircraft.

An approach to developing the new weather avoidance mode of airborne weather radar

2001 CIE International Conference on Radar Proceedings (Cat No.01TH8559), 2002
This paper is an approach to a new operational mode - the weather avoidance (WX AVOID) mode. The paper presents conceptual ideals concerning the acquisition of vertical information on weather (WX) targets, the manner of azimuth scanning while scanning vertically, weather data filtering and an indication scheme for quasi-three-dimension weather ...

Simulation Research on Wind Shear Prediction of Airborne Weather Radar

2014 International Conference on Virtual Reality and Visualization, 2014
Low-level wind shear will have serious interference to the aircraft during taking off and landing period, even causes the aircraft crash, function for wind shear prediction is meaningful to airborne weather radar system. This paper designs an airborne wind shear prediction simulation system referring to Collins WXR-2100 airborne weather radar.

Airborne Weather Radar Cloud Simulation Based on Fractal Theory

Advanced Materials Research, 2014
This paper describes a cloud simulation method of an airborne weather radar simulator based on the atmosphere characteristics of real clouds. With the fractal theory, an improved Successive Random Additions (SRA) to instruct cloud data modeling was chosen and an appropriate locus of control surfaces was selected.

Ground clutter censoring for airborne weather radar employing DEM

Proceedings of 2011 IEEE CIE International Conference on Radar, 2011
A ground clutter rejection method based on Digital Elevation Model (DEM) is proposed, which can be used to censor the clutter when airborne weather radar operates in weather mode. The theory of visibility analysis is used to identify the ranges with clutter.
