Fusion of telescopic and Doppler radar data
The most usual ways of observation of satellites and space debris and measurement of their orbits are • telescopic images, • radar reflections, • laser measurements. We use two of these three modalities, we combine telescopic images with response of Doppler radars. We use single images from a terrestrial telescope. Our radar is passive, we receive the signal of a distant terrestrial transmitter...
متن کاملImproved Doppler Radar/Satellite Data Assimilation
Our goal is to develop a short-term high-resolution data assimilation capability that can provide the Navy with improved analyses and forecasts of atmospheric conditions with sufficient detail and accuracy for supporting the Navy mission in threat detection, weapons deployment, and weather safe operations. The data assimilation system will utilize all available weather data, such as Doppler rad...
متن کاملProcessing of Doppler radar radial winds for data assimilation
Atmospheric wind field is 3-dimensional and variable over time and space. Doppler radar measures one component of the wind vector, ie. the radar radial component. For complete description of the wind field simultaneous measurements should be made with three Doppler radars. Usually only one radar is available and the availability of the other two radars is compencated by simplifying assumptions ...
متن کاملAnalysis of Radar Doppler Signature from Human Data
This paper presents the results of time (autocorrelation) and time-frequency (spectrogram) analyses of radar signals returned from the moving human targets. When a radar signal falls on the human target which is moving toward or from the radar, the signals reflected from different parts of his body produce a Doppler shift that is proportional to the velocity of those parts. Moving parts of the ...
متن کاملUse of Wind-Shear Displays for Doppler Radar Data
The usefulness of displaying vertical wind shear on a radar range height indicator is demonstrated. Fine structure in the pattern of shear is shown to be helpful for inferring general flow patterns and the occurrence of billows due to shearing (Kelvin–Helmholtz) instability.
