Doppler radar radial wind observations are modelled in numerical weather prediction (NWP) within observation errors which consist of instrumental, modelling and representativeness errors. The systematic and random modelling errors can be reduced through a careful design of the observation operator (Part I...
In 1993 the Federal Aviation Administration (FAA) began deploying two new wind shear detection systems: the Terminal Doppler Weather Radar (TDWR) and the third-generation Low Level Windshear Alert System (LLWAS 3). Currently, 9 airports are scheduled to receive both a TDWR and an LLWAS 3. Thi...
A muzzle velocity chronograph method and apparatus is described for measuring the velocity of a projectile (11) from a gun (13). In this method and apparatus a conventional radar Doppler signal from a radar device (15) is sampled and digitized by an analog-to-digital converter (23) and arr...
Doppler weather radar is a powerful tool to investigate the structure of the convective weather system, because it can provide fine temporal and spatial resolution data. The Doppler velocity is very useful to study the dynamic structure of the severe weather system. But it is more difficult to ...

1. A pulse-Doppler-radar device with an analysis circuit in the video position, which has devices for moving target indication and for secondary integration and with a CFAR-threshold for the implementation of ECCM-measures, characterized in that in order to produce a threshold value for the targ...
Micro-Doppler induced by mechanical vibration or rotation of structures in a radar target is potentially useful for target detection, classification and recognition. While the Doppler frequency induced by the target body is constant, the micro-Doppler due to vibrating or rotating structures of the tar...
Micro-Doppler signatures have been widely applied in civilian and military uses, In the paper, an overview of recent advances in extractions and applications of radar micro-Doppler signatures is presented, including recognition of space, air, and ground targets, combined micro-Doppler with range-Dop...
