A review of bistatic k-space imaging for electromagnetic prediction codes for scattering and antennas

Abstract: A bistatic k-space imaging concept for frequency-domain (FD) electromagnetic (EM) computer codes is presented. The concept enables the computation of images without the frequency sweep required for experimental images, resulting in a significant reduction in computational effort. This analytical imaging technique uses bistatic radiation computed from a generalized radiation integral. Images permit physical insight and understanding into how a radiation or scattering pattern is produced, by decomposition of the… Show more

“…The simulation is done with a fixed transmitter, and the receiver revolving round the scene-to-be-imaged at a fixed elevation angle and with the azimuth angle varying from 0º to 360º. The samples collected by FEKO can be shown to form points in the k space [24][25] domain of the scene being imaged. The projection of the k space data sampled by this combination is as given by the shaded area in Figure 6.…”

“…Notice that the total bandwidth of the pulse (between the zero-crossing points) is 2 GHz. However, the value of 1 GHz listed above represents the effective pulse bandwidth (for a definition of the effective pulse bandwidth, see reference [13]). …”

“…Notice that the total bandwidth of the pulse (between the zero-crossing points) is 4 GHz. However, the value of 2 GHz listed above represents the effective pulse bandwidth (for a definition of the effective pulse bandwidth, see reference [28]). We picked such a high value for the pulse bandwidth in order to obtain a very fine radar downrange resolution (in this case, 7.5 cm).…”
