Polyphase Coding for Weather Radars
IGARSS 2020 - 2020 IEEE International Geoscience and Remote Sensing Symposium, 2020In this paper, we describe the evolution of a pair of polyphase coded waveform for use in second trip suppression in a weather radar. The polyphase codes were designed and tested on NASA weather radar. The NASA dual frequency, dual polarization Doppler radar (D3R) was developed primarily as a ground validation tool for the GPM satellite dual frequency ...

Polarimetric FMCW weather radar
2015 23nd Signal Processing and Communications Applications Conference (SIU), 2015This study which was conducted as a Master's thesis, is a radar system working at X band. In this system, a 2 Watt continuous electromagnetic wave which is modulated with frequency ramp of 30 MHz bandwidth is generated and radiated through TX antenna. The scattered signal from the hydrometeors is multiplied with the transmitted one and beat signal is ...

Journal of Navigation, 1948
AbstractThe paper is divided into two parts.Part 1, under the heading of Non-standard Propagation, concerns variations in the apparent performance of marine navigational radar in its use for detecting shipping and land targets. The effects of changes in the density of the lower layers of the atmosphere on radar transmissions, their distortion of radar ...

UAV-Aided Weather Radar Calibration
IEEE Transactions on Geoscience and Remote Sensing, 2019Weather radar is well recognized as an effective sensor for obtaining the microphysical and dynamical properties of precipitation at high spatial and temporal resolution. Radar calibration is one of the most important prerequisites for achieving accurate observations.

Proceedings International Radar Conference, 2002
The Federal Aviation Administration has established three ground-based weather radar programs. The terminal Doppler weather radar (TDWR) and weather system processor (WSP) provide wind shear detection capability for air traffic controllers in the terminal area. These systems also reduce weather related delays. The next generation weather radar (NEXRAD)

2020 IEEE Radar Conference (RadarConf20), 2020
Modern ground-based weather radars are mostly dual-polarized, and they are rich in information content in multiple dimensions, and are ideal candidates for effective artificial intelligence (AI) applications. There are a large number of dual-polarization radars around the world.
