Target and Clutter Characteristics
2009The operation of all active sensors requires that some of the energy transmitted by the device be reflected off objects within the beam. The characteristics of the reflected signal can then be analyzed in various ways to extract information about the target.

Analysis of Clutter Characteristics of Integrated Sensor Is Structure
IET International Radar Conference 2013, 2013Clutter characteristics of Integrated Sensor Is Structure (ISIS) are researched in this paper. Conclusions are deduced from numerical simulation of the radiation pattern and clutter distribution. Taylor weighting depresses the amplitude of clutter from side-lobe, and also depresses the amplitude of the target echo from main-lobe.

Study on the Spectral width Characteristic of Scattering Clutter from Sea Surface
IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium, 2019In view of the influences of spatial resolution, time sampling length and SWH (significant wave height), a spectral width model is established. The theoretical results based on the model demonstrate the spectral width becomes wider with the resolution unit and time sampling length, but eventually tends to be constant.

Dual-Polarization Radar Characteristics of Wind Turbines With Ground Clutter and Precipitation
IEEE Transactions on Geoscience and Remote Sensing, 2016The demand for renewable power production has fostered an exponential increase in the size and number of wind turbines. This expanding source of power generation is sometimes at odds with maintaining the effective operation of radar systems in air traffic control, defense, weather prediction, and severe-storm-tracking applications.

Target detection within sea clutter based on combined fractal characteristics
2017 20th International Conference on Information Fusion (Fusion), 2017Using fractal dimension or one of other fractal characteristics to detect targets in sea clutter, it is often difficult to distinguish at low signal-to-clutter ratios. To solve this problem, a new method for target detection in sea clutter based on combined fractal characteristics is proposed.

Clutter loss characteristic in mm-Wave bands for small urban environment
2017 International Conference on Information and Communication Technology Convergence (ICTC), 2017This paper describes the clutter loss characteristic for the building clutter losses in millimeter wave bands for small urban city in Republic of Korea. The measurement campaign has been performed to a small town in Daejeon city, which was selected to represent the over-rooftop regions of urban low rise environment.

Modeling and characteristics analysis of clutter for passive radar on moving platform
2014 XXXIth URSI General Assembly and Scientific Symposium (URSI GASS), 2014In the latest years, the investigation of passive radar on moving platform (PRMP) for surveillance purpose has received a new interest. The problem of direct path interference and ground (sea) clutter is encountered in PRMP. This paper studies the modeling and characteristics of the clutter in PRMP which employs digital radio and television ...

Characteristic Investigation of Ionospheric Clutter of a Coastal High-Frequency Radar
2018 OCEANS - MTS/IEEE Kobe Techno-Oceans (OTO), 2018High frequency (HF) radar can overcome the limits caused by the curvature of the earth when its electromagnetic wave operated over high conductivity sea water. The HF radar spectrum is critical for large-area current mapping because of mechanism of Bragg resonance.

The Non-Stationary Characteristic Analysis and Model of Sea Clutter of Fuze
2005 IEEE International Symposium on Microwave, Antenna, Propagation and EMC Technologies for Wireless Communications, 2006Considering the actual sea clutter, a fractal noise AM-FM model is proposed. Based on the observed data of the sea clutter of fuze, for the first time, the fractal characteristics of fuze including the fractal dimension and multi-fractal are investigated.
