WebJul 1, 2024 · Introduction. High range resolution, a rapid scanning antenna and scan-to-scan integration technologies are generally applied for detecting small slowly moving sea-surface targets [], e.g. the periscope.However, for the wideband radar, the sea-clutter amplitude statistics are very long tailed and highly correlated [].This leads to high false alarm rate for … WebNov 29, 2024 · The jointed-feature detector for the floating small target in sea clutter is addressed in the paper. For the traditional energy-based detectors, it is difficult to detect the low...
A Novel Method of Small Target Detection in Sea Clutter
WebSep 18, 2024 · 2.1 Detection problem of floating small target in sea clutter Suppose that the radar transmits a coherent pulse train of length N at a beam position. When the cell under test (CUT) includes the returns with target, the CUT consists of target returns and sea clutter and noise; otherwise, the CUT consists of sea clutter and noise. WebSep 9, 2024 · It is challenging to detect small-floating object in the sea clutter for a surface radar. In this paper, we have observed that the backscatters from the target brake the continuity of the underlying motion of the sea surface in the time-Doppler spectra (TDS) images. Following this visual clue, we exploit the local binary pattern (LBP) to measure the … hearthwood condos
Dim and Small Target Detection in Multi-Frame Sequence Using Bi …
WebFeb 24, 2024 · It is a big challenge to detect and track small infrared marine targets in non-stationary and time-varying sea clutter because the signal is too strong to be estimated. Based on the phenomenon that sea clutter spreads not only in the temporal domain but also in the spatial domain, this paper proposes an infrared small marine target detection … WebJul 19, 2004 · Small-target detection in sea clutter. Abstract: Sea clutter in marine surveillance radar makes the task of detecting small targets a very challenging problem. In this paper, a set of three signal processing techniques designed to suppress unwanted … WebSep 1, 2024 · According to Monte Carlo simulation results, the proposed graph-based signal (target) detection method leads to the outstanding performance, compared to other existing techniques, especially when the signal-to-noise ratio is rather small (0–6 dB). In this paper, a novel robust graph-based adequate and concise information representation paradigm is … mounting brackets for outdoor light fixtures
