Terminal Doppler Weather Radar (TDWR) is a Doppler weather radar system with a three-dimensional "pencil beam" used primarily for the detection of hazardous wind shear conditions, precipitation, and winds aloft on and near major airports situated in climates with great exposure to thunderstorms in the United States. As of 2011, all were in-service with 45 operational radars, some covering multiple airports in major metropolitan locations, across the United States & Puerto Rico. Several similar weather radars have also been sold to other countries such as China (Hong Kong). Funded by the United States Federal Aviation Administration (FAA), TDWR technology was developed in the early 1990s at Lincoln Laboratory, part of the Massachusetts Institute of Technology, to assist air traffic controll

| - Un radar meteorológico Doppler de aeropuerto (en inglés, Terminal Doppler Weather Radar, TDWR) es un radar meteorológico Doppler instalado en la terminal de un aeropuerto para detectar precipitaciones y cizalladuras de viento para las necesidades de información del control del tráfico aéreo. Los radares TDWR conforman una red o un sistema radárico desplegado en los principales aeropuertos de los Estados Unidos expuestos a condiciones de cizalladura. En 2009, había cuarenta y cinco de esos radares meteorológicos a través de los EE. UU. y además uno en Puerto Rico, y al menos uno comprado por otros países como el de Hong Kong (China). El desarrollo de estos radares fue financiado por la Administración Federal de Aviación, y se realizó a principios de la década de 1990 por los Lincoln Laboratories, una componente del Massachusetts Institute of Technology. La principal ventaja de los TDWR, en comparación con los radares anteriores es su mayor resolución, y el rango angular, debido a su delgado haz y, mejorados algoritmos para el procesamiento de señales.

Le développement de ces radars a été financé par le Federal Aviation Administration (FAA) et effectué par Lincoln Laboratories, une composante du Massachusetts Institute of Technology. L’avantage principal des TDWR, par rapport aux radars antérieurs, est sa meilleure résolution, angulaire et en portée, due à son faisceau plus mince et à des algorithmes de traitement du signal. (fr)

Several similar weather radars have also been sold to other countries such as China (Hong Kong). Funded by the United States Federal Aviation Administration (FAA), TDWR technology was developed in the early 1990s at Lincoln Laboratory, part of the Massachusetts Institute of Technology, to assist air traffic controllers by providing real-time wind shear detection and high-resolution precipitation data. The primary advantage of TDWRs over previous weather radars is that it has a finer range resolution—meaning it can see smaller areas of the atmosphere. The reason for the resolution is that the TDWR has a narrower beam than traditional radar systems, and that it uses a set of algorithms to reduce ground clutter. (en)
