For further information contact us at helpdesk@openaire.eudescription Publicationkeyboard_double_arrow_right Article 2010 Netherlands EnglishWe have developed a novel diffraction grating based on lithographical techniques and anisotropic etching in silicon. The grating is designed for the short-wave-infrared channel of the TROPOMI imaging spectrometer that will be launched on ESA's Sentinel 5 Precursor mission to monitor trace gases in the earth atmosphere. Stringent requirements on both the imaging properties and the quality of the spectra translate to a high-tech grating. In our design the dispersion and resolution is increased with a factor 3.4 with respect to conventional gratings by using the grating in immersion, such that diffraction takes place inside the silicon grating material. By lithographic patterning and anisotropic etching of the mono-crystalline silicon we precisely control line spacing and blaze angle. The grating has a line spacing of 2.5 μm and is operated in sixth order. We show that an efficiency of 60% is reached on a 50 x 60 mm2 grating surface. We compare our test results with numerical calculations for grating efficiency for both polarizations and find good agreement. © 2010 Copyright SPIE - The International Society for Optical Engineering.

The Canadian SAR 580 system visited testsites during a 1 month period. Imagery was acquired in X, C and L band. Since several experiments called for calibrated measurement values, a calibration program was added, consisting of flights over calibration sites in the UK and Germany. On these site corner reflectors were set up. The results of this calibration will be presented to all participants. One of the test sites in The Netherlands was located in the Flevopolder, an agricultural area. During the growing season and especially during the SAR-580 flights scatterometer measurements were made here. The Dutch digital SLAR system operated at the same time. The knowledge on the radar signature of crops can be used to calibrate the SAR-580 images, like it has been done for the Dutch digital SLAR system. Unfortunately the quality of the SAR-580 data was too bad to enable this calibration and to compare the data with our SLAR system and scatterometer. Nevertheless the method is worthwile te be reported.

For further information contact us at helpdesk@openaire.eudescription Publicationkeyboard_double_arrow_right Article 1992 Netherlands EnglishThe Dutch PHARUS project aims for the developrlenÈ of a polarimetric C-band aircraft SAR, to be finalized in 1994. The PHARUS systen consists of three subsystens: the radar, the subsystem for the onboard data processing and recording and the ground-based subsystem for SAR processing. PHARUS is a very flexible system with numerous operating modes, intended for renote sensing research. Modes vary from a straighc forward single mode (e.g. HH polarisation)to a full polarimetric mode with alternating chirp patterns. This paper describes selected items of the onboard data processlng and recording subsystem, as it is under construction now. Data processing starts with high speed digitization of the offsec modulated radar slgnals. The digitized offsec modulated signals are demodulated and re-sampled (in range) to complex base band signals. A low pass filtering and decimation in flight direction is performed. Finally, pulse cornpression is performed based on FFT and IFFT.

The grating is designed for the short-wave-infrared channel of the TROPOMI imaging spectrometer that will be launched on ESA's Sentinel 5 Precursor mission to monitor trace gases in the earth atmosphere. Stringent requirements on both the imaging properties and the quality of the spectra translate to a high-tech grating. In our design the dispersion and resolution is increased with a factor 3.4 with respect to conventional gratings by using the grating in immersion, such that diffraction takes place inside the silicon grating material. By lithographic patterning and anisotropic etching of the mono-crystalline silicon we precisely control line spacing and blaze angle. The grating has a line spacing of 2.5 μm and is operated in sixth order. We show that an efficiency of 60% is reached on a 50 x 60 mm2 grating surface. We compare our test results with numerical calculations for grating efficiency for both polarizations and find good agreement. © 2010 Copyright SPIE - The International Society for Optical Engineering.

The PHARUS systen consists of three subsystens: the radar, the subsystem for the onboard data processing and recording and the ground-based subsystem for SAR processing. PHARUS is a very flexible system with numerous operating modes, intended for renote sensing research. Modes vary from a straighc forward single mode (e.g. HH polarisation)to a full polarimetric mode with alternating chirp patterns. This paper describes selected items of the onboard data processlng and recording subsystem, as it is under construction now. Data processing starts with high speed digitization of the offsec modulated radar slgnals. The digitized offsec modulated signals are demodulated and re-sampled (in range) to complex base band signals. A low pass filtering and decimation in flight direction is performed. Finally, pulse cornpression is performed based on FFT and IFFT.
