any ocean surface signatures in synthetic aperture radar (SAR) imagery are characterized by relatively low normalized radar cross section values. Distinguishing among these signatures objectively can be very difficult, especially with only the singleband and single-polarization SAR imagery available from the European Remote Sensing satellites and the Canadian Radarsat-1. Nevertheless, distincti...

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...

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...

In this paper, a new method for radar cross section reduction of a monopole antenna is proposed. In this method, a plasma helix like fluorescent bulbs is placed around the antenna element. The selected plasma parameter for this medium acts as an absorber without disturbing the antenna performance. The simulations show that radar cross section of simulated antenna is reduced in a wide frequency ...

The relationship between ocean wind vectors and L-band normalized radar cross sections (NRCS) is comprehensively examined to propose an L-band model function by using the Phased-Array L-band Synthetic Aperture Radar (PALSAR) and scatterometer wind data. Based on more than 90,000 match-ups, the L-band NRCS dependence on wind speed, incidence angle, and relative wind direction is modeled for the ...

-Measurements of the normalized radar cross section (_o) made by the YSCAT nltrawideband scatterometer during an extended deployment on the Canada Centre for Inland Waters (CCIW) Research Tower located at Lake Ontario are analyzed and compared with anemometer wind measurements to study the sensitivity of cr° to the wind speed as a function of the Bragg wavelength. This paper concentrates on upw...

The Ingara X-band fully-polarimetric medium grazing angle sea clutter data set was collected in the Australian maritime environment over an angular range of 360◦ in azimuth and 15◦ to 45◦ in grazing. This paper reports further analysis of this data set, focussing on understanding the azimuth variation to enable improved simulation accuracy and extraction of relevant geophysical parameters. This...
