Simultaneous observations using multiple ~300 MHz subbands, incorporated into the PSR/CX instrument, have provided one means of interference mitigation that is useful under moderately contaminated conditions. ETL has developed a new C-band spectrometer that observes emissions within relatively narrower bandwidths and is tunable from 5.8 to 7.5 GHz. The spectrometer is able to reduce the effects of the interference at the expense of radiance sensitivity and observation time. Preliminary data analysis suggests the spectrometer to be an effective component for improving the accuracy of remotely sensed soil moisture measurements using C-band radiometry.","PeriodicalId":198871,"journal":{"name":"Proceedings. 2005 IEEE International Geoscience and Remote Sensing Symposium, 2005.

Since power loss due to saturation from the raw data is not the same as the power loss from the image, a correction method including two steps for the saturated SAR data was proposed. Firstly, power compensation based on raw data for distributed targets was presented. The next, compensation for the differences between power loss from image and it from raw data was performed through analyzing the relation between gain alteration of image processors and standard deviation from ADC output data. The proposed method was verified by using simulated radar data and also Radarsat-1 SAR data.","PeriodicalId":198871,"journal":{"name":"Proceedings. 2005 IEEE International Geoscience and Remote Sensing Symposium, 2005.

For mapping and monitoring the spatial distribution of it using remote sensing data, a thorough understanding of their spectral behaviour is of paramount important. This paper presents an approach to estimating soil salinity through correlation and regression analysis between the EC with R(reflectance ), A(log(1/R)),and their derivatives respectively. The field spectral data is obtained by using ASD. We got 28 points in Aibi lake in Xinjiang,China, in July,2004. The results show that A' yield the highest performance in the calibration stage. The selected wave bands are 0.45-0.51μm,2.295-2.365μm. SEC is 37.3141, R 2 is 0.48 and a of constant, band1,band2 is 0.056,0.008,0.013. On the whole, we can accept that these two bands are the sensitive bands to soil salinity, and the regression procedure of A' can give a quantitative model for estimating EC. From previous theories and experiment results of other people, soil salinity has a high reflectance in blue band and a carbonate absorption festure is also reported. Our outcome is accord with it. It should be noted that we also need more data to validate it.

There is a great need to detect and monitor the land cover change in rapid urban expansion using remote sensing, accurately and timely, for planning and management. However, change detection capabilities are intrinsically limited by the spatial resolution of the digital imagery in urban. The application of multi-sensor data provides the potential to more accurately detect land-cover changes through integration of different features of sensor data. This paper integrated SPOT-5 XS data (10 m resolution with shortwave infrared band of 20 m resolution) and ETM+ Pan data (15 m resolution) and applied principal component analysis (PCA) of multi-sensor data to detect changes.

Several hundred million tons of sediment are transported to the coast and to the sea nearby annually, so the Yellow River Delta is in a continuous dynamic state due to interactions of river sediments and marine erosion. In this paper, the coastline evolution in the delta from 1976 to 2004 were studied using multi-temporal remote sensing images since the river course of the Yellow River was changed to Qing Shui Gou channel artificially in 1976. Trying to anatomize the spatio-temporal feature of coastline evolution, 21 sheets of Landsat images were used as the data source. The multi-temporal satellite images were rectificated precisely and registered each other, and all the images have the same coordinate system. A mean high water (MHW) model was developed for extracting coastlines, and the coastlines were extracted automatically from remote sensing images after supervised classification. The result shows that a new land of 323 km(2) was formed during the period of 1976 to 1999 in the present estuary by GIS overlay analysis, but a territory of 31 km(2) was eroded after 1999. Meanwhile, a territory of 153 km(2) was eroded in the Diaokou estuary area to the north of the Yellow River Delta from 1976 to 2004.","PeriodicalId":198871,"journal":{"name":"Proceedings. 2005 IEEE International Geoscience and Remote Sensing Symposium, 2005.

To what extent we can improve the estimates depends on how well we can combine radar reflectivity data at the two frequencies and other available information. To use the reflectivity data at 13.6 GHz and 35.5 GHz effectively, we need to refine the storm model that is used in the TRMM PR algorithm. The uncertainties in the model will directly result in the estimation error. This paper examines the major uncertainties in the possible DPR rain retrieval algorithm. They consist of two kinds of errors, i.e., errors related to hardware and inherent fluctuation of signals and errors related to storm and surface models. The former includes radar calibration errors, data fluctuation due to fading, data quantization error, and beam mismatching, and the latter includes biases caused by misidentification of the phase state of hydrometeors and by non-uniform distribution of precipitation within a field of view to name a few.","PeriodicalId":198871,"journal":{"name":"Proceedings. 2005 IEEE International Geoscience and Remote Sensing Symposium, 2005.

Foliard","doi":"10.1109/IGARSS.2005.1526577","DOIUrl":"https://doi.org/10.1109/IGARSS.2005.1526577","url":null,"abstract":"Low Flying enables higher resolution imaging capabilities within a given instrument and satellite format, but at price of higher atmospheric drag and propulsion constraints if we keep with circular orbit. The intuitive interest of elliptic orbit is to enable low altitude flight with much less atmospheric drag since it occurs during the limited duration of perigee. The working restriction to perigee leads to coverage limitation within a latitude window of 30°. This is not a fundamental obstacle since there are (will be) in the world several regional concentrations of needs for high resolution civilian or military surveillance. For the only goal of high resolution near the vertical of the satellite, the elliptic has no equivalent, but under given coverage and revisit constraints the circular orbit reduces the need for offnadir steering and the resulting degradation of (optical) resolution with respect to vertical. The purpose of this preliminary study is to compare the two orbit approaches. This is based on existing formats of satellite designed to fly above the usual altitude floor (500 km) and therefore according to limited mass extension (~15%) to accommodate the extra ∆V and propulsion needs (electrical or chemical). Emphasis is given to the microsatellite format (<200 Kg). It comes up that the elliptic orbits can be very efficient solutions when the imaging needs are geographically concentrated (1000 km circle). We can have constellations of satellites on circular orbits giving the global coverage, plus one or few extra satellites placed on elliptical orbits to drastically upgrade both the resolution and the revisit over one or several theatres with tuneable locations. I BACKGROUND AND OBJECTIVES Unlike circular orbits, elliptic orbits allow for flights at low altitude without too much erosion due to atmospheric drag. They therefore favour, for a given instrument and satellite envelope, optical or radar resolution performance in the perigee zone. The coverage is necessarily limited in terms of latitude, but probably suited to the emerging needs of “theatre observation” (high resolution and revisit on a limited region). The purpose of the study is to precise opportunities of elliptic orbits in comparison with unusually low circular orbits (resolution, coverage, revisit, capability to move the theatre) within the reach of existing formats of satellite bus already used for circular orbits, that is to say according to less than 10% 15% satellite extra mass for propulsion. Particular attention is given to Micro satellite Format (Myriade< 150 kg), and indications are given for Pléïades (1tonne) or even Helios ( 2 to 4 tonnes). This study has been performed within the CNES organisation in charge of preliminary studies, called PASO (Plateau for Architecture of Orbital Systems).
