Doppler Weather Radar Velocity Measurements Using a Single Pulse

Single-shot Doppler Velocity Estimation using double chirp pulse compression

Coherent ultrasonic Doppler velocimeters provide precise and accurate measurements of velocity profiles in many applications. However, these instruments suffer from the well known range-velocity ambiguity, making this kind of instruments not well suited for velocity measurements in channels of several meters depth and water velocities of some meters per second. On the other side, incoherent ult...

Performance comparison of pulse-pair and wavelets methods for the pulse Doppler weather radar spectrum

In the civilian aviation field, the radar detection of hazardous weather phenomena (winds) is very important. This detection will allow the avoidance of these phenomena and consequently will enhance the safety of flights. In this work, we have used the wavelets method to estimate the mean velocity of winds. The results showed that the application of this method is promising compared with the cl...

Three-Dimensional Simple Adjoint Velocity Retrievals from Single-Doppler Radar

In this paper, the original simple adjoint method of Qiu and Xu is improved and tested for retrieving the 3D storm-scale wind field from single-Doppler radar data. The method incorporates single-radar data and background fields, along with a dynamical constraint, smoothness, and anelastic mass continuity constraint, in a cost function. The minimization of the cost function, with the desired fit...

Wind observations with Doppler weather radar

Introduction Weather radars are commonly employed for detection and ranging of precipitation, but radars with Doppler capability can also provide detailed information on the wind associated with (severe) weather phenomena. The Royal Netherlands Meteorological Institute (KNMI) operates two identical C-band (5.6 Ghz) Doppler weather radars. One radar is located in De Bilt and the other one is loc...
