Bistatic radar target tracking is challenging due to the fact that measurements are nonlinear functions of Cartesian state. The converted measurement Kalman filter (CMKF) converts raw into coordinates prior and superior extended for certain problems. challenges CMKF debiasing approximating error covariance. Due no closed form biases, we utilize second-order Taylor series expansion conventional ...

The High-Resolution Wide-Swath (HRWS) Synthetic Aperture Radar (SAR) system, promoted by EADS Astrium GmbH, has been object in the last years of intensive studies for his capability to overcome the conflict between azimuth resolution and swath width of conventional SAR. The original choice of a bistatic solution for the system architecture has been recently reconsidered and is currently oriente...

Radar remote sensing deals with the extraction of object information from electromagnetic wave parameters. To fully exploit the potential of acquiring quantitative information requires a detailed description of the interaction between microwaves and objects. For practical reasons a simplified approach is preferred where the radar return of a distributed target is modeled as a sum of scatterer e...

The Measured Equation of Invariance (MEI) method has received considerable attention recently. Unlike more traditional numerical techniques, MEI solutions are obtained by inversion of a relatively small and sparse matrix. Therefore, the MEI method can potentially provide a solution much more quickly than other techniques. To date, the MEI method has been applied primarily to discrete objects. I...

With appropriate geometry configurations, bistatic Synthetic Aperture Radar (SAR) can break through the limitations of monostatic SAR on forward-looking imaging. Thanks to such a capability, bistatic forward-looking SAR (BFSAR) has extensive potential applications. For the focusing problem of BFSAR, wavenumber-domain algorithm is accepted as the ideal solution. However, in practical application...

In the last years, an important amount of research has been headed towards the measurement of above-ground forest biomass with polarimetric Synthetic Aperture Radar (SAR) tomography techniques. This has motivated the proposal of future bistatic SAR missions, like the recent non-cooperative SAOCOM-CS and PARSIFAL from CONAE and ESA. It is well known that the quality of SAR tomography is directly...

This paper completes the fundamental development of the basic coherent entities in Radar Polarimetry for coherent reciprocal scattering involving polarized wave states, antenna states and scattering matrices. The concept of antenna polarization states as contravariant spinors is validated from fundamental principles in terms of Schelkunoff’s reaction theorem and the Lorentz reciprocity theorem....

CFAR (Constant False Alarm Rate) detectors were designed and evaluated in non-homogeneous DVB-T (Digital Video Broadcasting-Terrestrial) passive radar scenarios. The CA-CFAR (Cell-Averaged CFAR) is the most widespread incoherent CFAR technique. CA-CFAR detector is optimal under the assumption of homogeneous interference, but CA-CFAR performance is degraded when this assumption is not fulfilled....
