Snow Depth on Arctic Sea Ice Retrieval Using a Synergy of Sentinel‐3's Active and Passive Microwave Instruments

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Snow depth remains one of the largest sources of uncertainty in satellite‐derived sea ice thickness (SIT). Here, we introduce the novel Nadir Radiometer and Radar Synergy (NaRRS) method that combines data from Sentinel‐3's Microwave Radiometer (MWR) and Synthetic Aperture Radar Altimeter (SRAL) to retrieve Arctic snow depth on sea ice.

Application of Artificial Neural Computation in Topex Waveform Data

, 2009
Using the TOPEX radar altimeter for land cover studies has been of great interest due to the TOPEX near global coverage and its consistent availability of waveform data for about one and a half decades from 1992 to 2005.

Response characteristics of ground-penetrating radar for subgrade void based on random reconstruction of soil-rock mixture

Yantu gongcheng xuebao
In order to study the response characteristics of geological radar waves to soil-rock mixed subgrade void, a microscopic model of soil-rock mixture with pores is built with considering the randomness and non-uniformity of soil-rock mixtures.

LPI Radar Waveform Modulation Recognition Based on Improved EfficientNet

Electronics
To address the challenge of low modulation recognition accuracy for Low Probability of Intercept (LPI) radar waveforms under low Signal-to-Noise Ratio (SNR) conditions—a critical limitation in current radar signal processing research—this study proposes a novel recognition framework anchored in an improved EfficientNet model.

SOME RADAR TOPICS: WAVEFORM DESIGN, RANGE CFAR AND TARGET RECOGNITION [PDF]

, 2006
The first RADAR patent was applied for by Christian Huelsmeyer on April 30, 1904 at the patent office in Berlin, Germany. He was motivated by a ship accident on the river Weser and called his experimental system ”Telemobiloscope”. In this chapter some important and modern topics in radar system design and radar signal processing will be discussed ...

Cognitive radar waveforms for frequency dense environments

, 2017
© 2017 IEEE. A wideband cognitive radar operating in spectrally dense environments needs to use special adaptive waveforms, in order to mitigate the effect of the interferences caused by a number of concurrent narrow band communication services.
