“…The line Γ 1 intersects the upper circularity of the BT at B and C and the line Γ 2 intersects the lower circularity at D and E. Theoretical computing and measuring experiments show that the backscattering of the BT is usually contributed by the sliding-type scattering centers A, B, C, D and E as shown in Fig. 1 [7,27]. The vectors of oA, oB, oC, oD and oE are defined as…”

“…[1][2][3][4][5]. The precession of the ballistic target (BT) is also a typical kind of micro-motion dynamics [6,7]. Targets with micromotion dynamics induce additional time-varying frequency modulation and generate sidebands about the Doppler frequency which is called micro-Doppler (m-D) effect [8].…”

“…Micro-Doppler is regarded as a unique signature of an object with movements where the uniqueness means different micro-motions have dissimilar signatures. Micro-Doppler signatures might be extracted for radar target identification which is seen as a good method and a technique of great potential [6,7,[9][10][11][12][13][14][15][16][17]. Since the m-D phenomenon is presented and researched by Chen et al, the extractions of the m-D signatures have developed rapidly [8,[18][19][20][21][22].…”

“…The cost burden of utilizing the EHT with six parameters is huge and the extracted features easily run into local optimums. Wang et al [7] put forward a method to estimate the precession frequency and the precession angle, but not all the six features can be extracted by this method. Therefore, it is necessary to propose a method to extract the four precession features and two structural parameters simultaneously.…”

Abstract-It is potentially useful to perform target identification using micro-Doppler features because they contain information on the geometrical structure of the target. In this paper, the m-D effect of the rotationally symmetric ballistic target (BT) is analyzed which reveals that the m-D is not a form of sinusoidal modulation due to the slidingtype scattering. Inspired by the extended Hough transform (EHT), a method to extract all the six parameters of the BT is proposed. The m-D effect and the performance of feature extraction algorithm are demonstrated by the measured data in a microwave anechoic chamber.

Abstract-Imaging and scaling of precession targets are very important in spatial target surveillance. The bistatic wideband radar echo model of the spatial precession cone-shaped target is induced, and bistatic ISAR imaging method based on time-frequency analysis is described. Combined with the monostatic and bistatic scattering characteristics of cone-shaped targets, the cross scaling method is presented through range instantaneous Doppler (RID) image matching using T/R-R bistatic radar observations, and the correct scaled monostatic and bistatic two-dimensional images can be obtained at the same time, which can reflect the actual size of the target. The algorithm is validated by dynamic simulation with electromagnetic computation data and provides a feasible way for the stable recognition of spatial targets.
