“…The error obtained using other glint analyses is the same as that in (14), [7], [22], [23], though the arctangent of the error term should be used [24]. This similarity led Neri to define a cross-eye gain as the error term divided by e giving [3] G C = 1 0 a 2 1 + a 2 + 2a cos() (15) and this cross-eye gain appears in (12).…”

Abstract-An extended and rigorous analysis of retrodirective cross-eye jamming in a radar system scenario is presented. This analysis removes the approximations that limit the validity of other analyses of cross-eye jamming. These results imply that under certain conditions, a monopulse radar system can be more easily deceived than suggested by conventional cross-eye analyses. Furthermore, the cross-eye jammer antenna patterns do not affect the induced monopulse error.

“…Two types of glint generation theories of glint are accepted by the majority: the tilt of electromagnetic energy flow [8] and phase perturbation [2] theory. The first one is realized by the calculation of energy flow of the scattering field; the second is applied in the phase simulations of angular glint and is accurate compared with measurement results.…”

“…Since 1959, when the concept of glint was firstly proposed, the radar angular glint has attracted great attention among electro-magnetic diffraction and stealth researchers [1][2][3]. The angular glint is a key signal in the generation of target loss probability in radars, for strong glint can give rise to tracking loss and misjudgment.…”

Abstract-In this paper, we present the chaotic verification for angular glint of complex radar target. Angular glint is a key factor in the generation loss probability in radar detections, and the intrinsic physical characteristic and suppression techniques of glint have been a hot topic in radar signal analysis. In this paper, the radar angular glint samples of a typical complex target are calculated by the Greco method based on Phase Gradient method. The simulated glint series fit the prerequisites of chaos for deterministic, nonlinear generation and no regularities in time domain, therefore the analysis the chaotic traits is required. We propose the design of chaotic verification flow, which is proved to be efficient and effective by the experiment of Lorenz Attractor signal model, and the details have been explained. The algorithm flow begins with the determination of optimum time lag and minimum embedding dimension, and is followed by the timedelay reconstruction in phase space. The results are presented with three qualitative verification results of attractor geometry, Poincare section and principal component analysis and two quantitative results of correlation dimension and largest Lyapunov exponent for the glint series. With comparison with results obtained by Lorenz attractor, the chaotic traits of angular glint data are verified. Therefore, the paper has proposed new possible reduction and prediction ideas to refrain angular glint in the digital processing unit of radar receiver in the future.

“…Linsday proposed PGM (phase gradient method) using the phase gradient to represent the effect of angular glint [2]. Dunn and Howard proposed PVM (Poynting vector method) when they found that there was a component of the time-averaged Poynting vector orthogonal to the radial direction [3].…”

“…And on this basis polarization was taken into consideration by Kajenski when angular glint was calculated and analyzed [5]. Previous research of angular glint mostly focused on dipoles [2][3][4][5] or canonical targets in free space [6]. However, radar targets cannot be divorced from the background such as sea or earth in practice.…”

Abstract-In this paper, angular glint characteristics of a two-dimension (2-D) perfect electric conductor (PEC) target above a PEC rough surface are investigated. The induced surface currents on the target and on the rough surface are obtained by employing the method of moments combining UV matrix decomposition technique (MOM-UV). Based on electromagnetic (EM) theory and the phasefront distortion concept of angular glint, the formulae of angular glint for 2-D target are proposed, and angular glint is calculated precisely by using phase gradient method (PGM). The analysis of the result is implemented by means of numerical extraction of the coupling currents and relationship between the phase front and angular glint, thus revealing the effects of the coupling on the angular glint.
