Abstract-Conventional interferometric ISAR (InISAR) imaging requires a radar system with at least three antennas, and the hardware complexity may be a main obstacle to practical realization. In this paper, we propose an InISAR three-dimensional imaging algorithm using only one antenna. Interferometric processing is carried out among ISAR images obtained during three near measurement intervals. The scatterer position in the range direction is obtained from range cell number in ISAR images, and the azimuth/height information is estimated from interferometric phases and geometrical relationship. Moreover, the target track requirements of the proposed method are also investigated. Simulations have shown the effectiveness of the proposed method.

“…InISAR imaging has been widely investigated [4][5][6][7][8][9][10][11][12][13]. However, it costs large for adding two or more additive antennas to the existing wideband radar system, which may be the main reason that no practical system appears up to now.…”

“…In imaging problems, observation data are often modeled by 2-D discrete random processes. However, many examples can also be found where data are 3-D such as, for instance, hyperspectral imaging (x-spatial dimension 2 y-spatial dimension 2 wavelength; see, e.g., [1]) or interferometric synthetic aperture radar (IF-SAR) imaging (x-spatial dimension 2 y-spatial dimension 2 elevation; see, e.g., [2] and [3]) for which multidimensional processing is used (see, e.g., [4]- [6]). Furthermore, in some applications, the data can be vector-valued (e.g., in array processing).…”

Abstract-In many detection and estimation problems associated with processing of second-order stationary random processes, the observation data are the sum of two zero-mean second-order stationary processes: the process of interest and the noise process. In particular, the main performance criterion is the signal-to-noise ratio (SNR). After linear filtering, the optimal SNR corresponds to the maximal value of a Rayleigh quotient which can be interpreted as the largest generalized eigenvalue of the covariance matrices associated with the signal and noise processes, which are block multilevel Toeplitz structured for -dimensional vector-valued second-order stationary -dimensional random processes x . In this paper, an extension of Szegö's theorem to the generalized eigenvalues of Hermitian block multilevel Toeplitz matrices is given, providing information about the asymptotic distribution of those generalized eigenvalues and in particular of the optimal SNR after linear filtering. A simple proof of this theorem, under the hypothesis of absolutely summable elements is given. The proof is based on the notion of multilevel asymptotic equivalence between block multilevel matrix sequences derived from the celebrated Gray approach. Finally, a short example in wideband space-time beamforming is given to illustrate this theorem.Index Terms-Asymptotic distribution, block multilevel Toeplitz matrix, generalized eigenvalues, multidimensional second-order vector valued stationary random process, Szegö's theorem.

As one of the most typical characteristics in space target motion, spin phenomenon has good 3D imaging application potential. Conventional target imaging algorithm fails to make full use of the rotating features of the target to obtain the characteristics of target space, and the speedy spin of targets will cause the dramatic changes in the positions of scattering center within short observation session, which may lead to the failure of imaging algorithm. Aiming at such a special phenomenon of the space target, the time frequency distribution curve of echoes in each scattering center could be mapped onto the parameter space to obtain the position of each scattering center by taking advantage of Hough transformation, thus the 3D features of spin target could be obtained. In this article, the 3D imaging algorithm was studied on the basis of Hough transformation, and its effectiveness was tested with simulation. Meanwhile, the translational motion and shielding effect of space target were discussed, and favorable imaging results were achieved.
