coregistration of optical and radar imageries is a major pre-processing step in many remote sensing applications including change detection and interferometric processing. specially, the coregistration faced more difficulties in radar imageries due to the high noise level and intense spatial-temporal decorrelation. hence, non-automatic coregistration methods are much more time consuming and ine...

the radar cross section of a target plays an important role in the detection of targets by radars‎. ‎this paper presents a new method to predict the bistatic and monostatic rcs of coated electrically large objects. ‎the bodies can be covered by lossy electric and/or magnetic radar absorbing materials (rams)‎. ‎these materials can be approximated by the fresnel reflection coefficients‎. ‎the pro...

The performance of multiple input multiple output (MIMO) radar configurations of distributed antennas are analyzed. Statistical multiple input multiple output (MIMO) radar develops angular diversity to mitigate the impact of radar cross section fluctuations (RCF). The fluctuations can be modeled with scattering model consists of non-orthogonal waveforms for fast target or radar cross section fl...

An experimental study of glacier ice detection in rain using X-band radar is presented. The radar data were collected in the Greenland Sea region in August 2013, using a cross-polarized X-band radar, capable of simultaneously measuring coand cross-polarized backscattered waves. The system was deployed on the Oden, a Swedish icebreaker. During the deployment, raw coand cross-polarized radar data...

radar cross section (rcs) calculation is an important issue of objects stealth and identification. it is necessary to design the rcs software because of the high cost of rcs measurements in practice. in this paper, designing of efficient software using physical optics theorem for radar cross section calculation of the complex perfect electric conductors or complex dielectric objects for high fr...

Radar sensor networks, including biand multi-static radars, provide several operational advantages, like reduced vulnerability, good system flexibility and an increased radar cross-section. However, radar-to-radar interference suppression is a major problem in distributed radar sensor networks. In this paper, we present a cross-matched filtering-based radar-to-radar interference suppression alg...

In June 2008, during the T44 swath, the Cassini SAR (Synthetic Aperture Radar) observed sinuous channels in the South-west of the Xanadu region (Fig. 1 and 2). Some parts of these channels exhibit very large radar cross-sections, up to 5 dB whereas the angle of incidence was ~20°. This is larger than allowed by the coherent backscatter model considered to explain the unusual reflective and pola...
