Refracted Propagation Distortion and Its Correction for Airborne Radar
نویسندگان
چکیده
This paper is devoted to the study of mathematical models for the refracted propagation effects and their correction for airborne radar tracking. Given an atmosphere of varying refracted index, the path of the EM radiation is curved and this causes bias errors on range and elevation radar measurements. First, we model these atmospheric errors and then we generate the corrupted measures. Second, we process the synthetic data to evaluate the induced bias of range and elevation errors. Finally, an algorithm, based on the Kalman Filter (KF) is proposed in order to reduce such errors and improve tracking performance. Both theoretical and numerical results are described.

Constrained Fast-time STAP Techniques for Interference Suppression in Multichannel SAR
Forming a Synthetic Aperture Radar (SAR) image while suppressing an airborne broadband jammer can potentially destroy large regions of the image. In addition to this, multipath reflections from the ground, known as hotclutter (HC) or terrain scattered interference will add a nonstationary interference component to the image. Using multiple antennas on a SAR provides spatial degrees of freedom a...

متن کاملArray Pattern Distortion and Remedies in Space–Time Adaptive Processing for Airborne Radar
Space–time adaptive processing (STAP) for airborne early warning radar has been a very active area of research since the late 1980’s. An airborne rectangular planar array antenna is usually configured into subarrays and then partial adaptive processing is applied to the outputs of these subarrays. In practice, three kinds of errors are often encountered, i.e., the array gain and phase errors ex...

A Mathematical model has been considered to study the reflection and refraction phenomenon of plane wave at the interface of an isotropic liquid medium and a triclinic (anisotropic) half-space. The incident plane qP wave generates three types of reflected waves namely quasi-P (qP), quasi-SV (qSV) and quasi-SH (qSH) waves in the tric...
