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.

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

Airborne weather radar as an instrument for automatic mapping

14th International Conference on Microwaves, Radar and Wireless Communications. MIKON - 2002. Conference Proceedings (IEEE Cat.No.02EX562), 2003
The classification of navigational radar landmarks and the principles of their display at automatic radar mapping are proposed. Selection algorithms of each type of navigational landmarks are developed. The priority of navigational landmark classes is established, and the scheme of the combining different channels is designed. The automated recognition

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.

The Implementation of Airborne Weather Radar in Simulation System

2019 14th IEEE Conference on Industrial Electronics and Applications (ICIEA), 2019
in this paper, a semi-physical system is established to simulate real airborne weather radar, which provides a training environment on the ground for flight crews. A display and control module (DCM) is designed in GL Studio software, and a serial port was adopted in DCM as a communication interface connected to a signal processing module.
