RPC modeling for spaceborne SAR and its aplication in radargrammetry
2010 IEEE International Geoscience and Remote Sensing Symposium, 2010The RPC (Rational Polynomial Coefficient) model can be used as a replacement sensor model for geo-coding spaceborne SAR data. A hybrid method, combining the L-curve and the IMCCV (Iteration method by correcting characteristic value) method, for solving ill-conditioned equations in the RPC model is proposed.

Evaluation of the RPC Model for Spaceborne SAR Imagery
Photogrammetric Engineering & Remote Sensing, 2010The rational polynomial coefficient (RPC) model has raised considerable interest in the photogrammetry and remote sensing community. Much work has been done on frame camera imagery and/or push-broom scanner imagery, and it has been widely accepted that the RPC model can be taken as an alternative to rigorous sensor models for photogrammetric processing.

Satellite SAR geocoding with refined RPC model
ISPRS Journal of Photogrammetry and Remote Sensing, 2012Recent studies have proved that the Rational Polynomial Camera (RPC) model is able to act as a reliable replacement of the rigorous Range-Doppler (RD) model for the geometric processing of satellite SAR datasets. But its capability in absolute geolocation of SAR images has not been evaluated quantitatively.

Simple models for RPC weighting fields and potentials
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2004Using conformal maps, formulae are derived and public (http://www.itp.tu-graz.ac.at/schnizer/Theory_of_Chambers/) Mathematica programs are developed giving the weighting potentials and fields in simple models approximating the electrode configurations in Gas Microstrip or Resistive Plate Chambers.

Modeling and evaluation of serial multicast remote procedure calls (RPCs)
IEEE Communications Letters, 2009The need for serial multicast remote procedure calls (RPCs) arises in many distributed systems to avoid network bottlenecks and high-latency links, especially when the caller wants to send a large amount of data to multiple callees. In this paper, we present a mathematical model of serial multicast calls in order to understand their performance ...

MOM vs. RPC: communication models for distributed applications
IEEE Internet Computing, 2005An important aspect of designing a distributed application is the communication model we use to connect its various components. Some middleware solutions, such as Web services, offer two of the most important communication paradigms: asynchronous messaging and remote procedure call (RPC).

A model of execution time estimating for RPC-oriented programs
1990This paper describes an execution time estimating model for programs which use Remote Procedure Calls (RPCs) as the tool for distributed computing. At first a general model with no closed-form solution is developed and a nondeterministic algorithm for its solution is given.

A general method of generating satellite epipolar images based on RPC model
2011 IEEE International Geoscience and Remote Sensing Symposium, 2011This paper presents a general method to generate the linear push-broom cameras and SAR epipolar images, which is based on RPC model and image-space adjustment model for relative orientation. The epipolar curves are derived by endpoints growing and fitted with straight lines and hyperbolas.

Biodynamic Pilot Modelling for Aeroelastic A/RPC
2013This work discusses the identification and the modeling of the biomechanics of fixed and rotary wing aircraft. The study is conducted within the European Commission 7th Framework Programme ‘Aristotel’ to understand the potential impact of involuntary pilot activity on the stability and the handling qualities of the vehicle, and to develop the ...

Evaluation of the RPC model as a replacement for the spaceborne InSAR phase equation
The Photogrammetric Record, 2011AbstractSynthetic aperture radar interferometry (InSAR) is an alternative to conventional stereoscopic SAR for extracting relative or absolute terrain elevation information. However, for different InSAR data‐sets, the auxiliary parameters are different, which introduces differences in the SAR interferometry rigorous sensor model (RSM).
