Wind shear signal simulation of the airborne weather radar

2011 IEEE RadarCon (RADAR), 2011
Wind shear is recognized by a major hazard during takeoff and landing of aircraft, which can be detected by airborne forward-looking weather radar. A high-fidelity wind shear model constructed by the Computational Fluid Dynamics software has been implemented in this study.

Vertical-Array-based Contour Reconstruction Algorithm for Airborne Weather Radar

2020 IEEE 11th Sensor Array and Multichannel Signal Processing Workshop (SAM), 2020
Aiming at meteorological target, in this paper, a new contour reconstruction algorithm is proposed against the disastrous weather. The algorithm is capable of reconstructing the specific contour of meteorological target by exploiting vertical array of airborne weather radar system.

Weather Detection with an AESA-Based Airborne Sense and Avoid Radar

2020 IEEE Radar Conference (RadarConf20), 2020
Modern radar systems shall provide multifunctional capabilities because airborne applications typically demand sensor equipment, which has optimized size, weight and power. Therefore the use of multifunctional sensors is necessary and efficient. This work represents the first weather radar data of flight tests of such an multifunctional AESA (Active ...

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 ...

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.
