From the high spectral resolution thermal infrared observations of the Infrared Atmospheric Sounding Interferometer (IASI) mineral dust AOD (transferred from thermal infrared to 0.5 μm) is retrieved using a Singular Vector Decomposition of brightness temperature spectra. As infrared retrieval based on 8–12 μm observations, dust observation with IASI is(More)
This paper describes a monolithic integrated transmitter intended for impulse radio (IR) Ultra-wide band (UWB) indoor communication and indoor localization. The transmitter operates in the higher UWB band centered at 7.25 GHz and generates impulses with bandwidth of 2.08 GHz. Consequently, the transmitter utilizes for communication and ranging complete UWB(More)
This paper presents a fully differential baseband pulse generator intended for Impulse-Radio Ultra-Wideband (IR-UWB) direct up-conversion transmitter architectures. The generator provides impulse related binary phase shift keying (BPSK) and on/off keying (OOK) modulation in accordance with the IEEE 802.15.4a standard. The logic part of the generator runs on(More)
One energy efficient way of ASIC implementation for the standard IEEE802.15.4a was considered in greater detail. The main focus was on developing a solution for short range communication based on impulse radio ultra wideband. The ASIC implementation is performed with the 250 nm SiGe technology from IHP, Germany. The current system consists of three chips:(More)
An information content analysis for multiwavelength SYNergetic AErosol Retrieval algorithm SYNAER was performed to quantify the number of independent pieces of information that can be retrieved. In particular, the capability of SYNAER to discern various aerosol types is assessed. This information content depends on the aerosol optical depth, the surface(More)
This paper describes a localization method for an IR-UWB (Impulse Radio Ultra Wideband) two-way ranging system developed for precise time-of-arrival measurements. The ranging system provides a time resolution of 275 ps, which allows precise indoor distance estimation with the accuracy of 4 cm. In this work, a two-way ranging algorithm has been extended into(More)
