Sensitivity Analysis of Brown Model Waveform in Radar Altimetry
In satellite altimetry (radar altimetry), the altimeter emits a pulse, with known power, to the earth surface and receives it back continuously to determine of the sea surface height. The time series of the mean returned power is recorded individually at satellite as the so-called waveform. Analytical model for the waveform is first introduced by Brown, which consists of six parameters: signif...
متن کاملWaveform aliasing in satellite radar altimetry Walter H. F. Smith and Remko Scharroo, NOAA Lab for Satellite Altimetry Beginning with Seasat and continuing through the design for Jason-CS, all satellite radar
Beginning with Seasat and continuing through the design for Jason-CS, all satellite radar altimeters have employed a pulse compression scheme known as full-deramp of a linear FM chirp. The process by which all conventional altimeters create a waveform from digitized radar echoes can lead to aliasing of the waveform. This was first noted by Bob Jensen in a 1999 paper (IEEE TGRS 37(2):651-658, do...
متن کاملWaveform Design using Second Order Cone Programming in Radar Systems
Transmit waveform design is one of the most important problems in active sensing and communication systems. This problem, due to the complexity and non-convexity, has been always the main topic of many papers for the decades. However, still an optimal solution which guarantees a global minimum for this multi-variable optimization problem is not found. In this paper, we propose an attracting met...
متن کاملTopex/Poseidon Satellite Altimetry
A recently developed multiresolution estimation framework offers the possibility of highly efficient statistical analysis, interpolation, and smoothing of extremely large data sets in a multiscale fashion. This framework enjoys a number of advantages not shared by other statistically-based methods. In particular, the algorithms resulting from this framework have complexity that scales only line...
متن کاملBasic Radar Altimetry Toolbox & Tutorial
The Basic Radar Altimetry Toolbox is a collection of tools, tutorials and documents designed to facilitate the use of radar altimetry data. It is able to read most distributed radar altimetry data, from ERS-1 & 2, Topex/Poseidon, Geosat Follow-on, Jason-1 and 2, Envisat, and the future Cryosat mission, to perform some processing, data editing and statistic, and to visualise the results. As part...
