README MIT license Repository description This repository contains a simple MATLAB simulation code that generates pulse Doppler radar signatures for four classes of helicopter-like targets. The dataset thus created is used to investigated AD deep and non-deep methods in a dedicated paper. The code ...
For example, the Doppler shift in ultrasound can be used to measure blood velocity, while police use the Doppler shift in radar (a microwave) to measure car velocities. In meteorology, the Doppler shift is used to track the motion of storm clouds; such “Doppler Radar” can give velocity ...
For the data capture, we used the same radar configuration through the entire research. The details of the data capture is shown below. "designed_frequency": 76.8 Hz, "config_frequency": 77 Hz, "range_size": 256, "maximum_range": 50 m, "doppler_size": 64, "azimuth_size": 256, "...
Calculation of the bias statistic over all azimuthal directions results in a near-zero value even in the presence of systematic differences between the measured and modelled wind speed and direction. This paper describes a method for bias estimation of Doppler-radar radial-wind observations. ...
It is worth mentioning that zero Doppler effect observed in the zero-index metamaterials is different from the concept of 'zero Doppler effect' in radar technology, which stands for a technique to compensate the normal Doppler frequency shift. The wave in the near zero-index medium has been ...

During the VOCALS 2008 cruise, a NOAA W-band (94 GHz) radar was mounted on a stabilized platform and pointed vertically to observe the marine boundary layer cloud structure. Occasionally during drizzle events, while the reflectivity was consistent with time and height, the estimated spectrum width...
Hi Dan. A reliable Raymarine product manager did tell me that he thought that their Quantum hardware could support Doppler features but he was not definite and there certainly is no time frame. One thing I’ve learned is that radar engineering is slow and hard. ARPA is a great example. Fu...
