This paper proposes a unified detection strategy against three kinds of attacks for multi-agent systems (MASs) which is applicable to both transient and steady stages. For on the communication layer, watermarking-based scheme with KullbackLeibler (KL) divergence designed. Different from traditional schemes, each agent transmits message set containing two state values different types watermarking. It found that performance determined by relevant parameters watermarking signal. Unlike existing...
Abstract. The full-waveform data is the core of GaoFen-7 (GF-7) satellite laser altimeter, and evaluation waveform quality an important step premise for altimetry control. In this paper, full assessment analysis GF-7 altimeter implemented during period on-orbit experiment, real many orbits used to quantitatively describe characteristic parameters transmitted signal-to-noise ratio (SNR), result two beam lasers compared. conclusion validated that can obtain effective echo availability...
We present a guided atom laser. A Bose-Einstein condensate (BEC) is created in crossed hybrid magnetic and an elongated optical trap, which acts as matterwave guide. Atoms are extracted from the BEC by radio frequency (rf) outcoupling then horizontal This method allows to control acceleration of beam achieve large de Broglie wavelength. also measure longitudinal energy laser using elements based on blue light barrier.
Satellite laser altimetry can obtain sub-meter or even centimeter-scale surface elevation data over large areas, but it is inevitably affected by scattering caused clouds, aerosols, and other atmospheric particles. This ranging error cannot be ignored. In this study, we systematically combined existing identification technology used in satellite observed that the traditional algorithm effectively estimate multiple of GaoFen-7 (GF-7) satellite. To solve problem, from GF-7 to analyze...
Slope and roughness are basic geophysical properties of terrain surface, also sources error in satellite laser altimetry systems. The full-waveform altimeter records the complete echo waveform backscattered from target surface worldwide, so it may be used for both range measurement inversion analysis geometric parameters surface. This paper proposes a new method slope bare or near-bare within footprint using data, Shuttle Radar Topographic Mission (SRTM) topographic prior knowledge. To solve...
