“…Bankman [9] presented an analytical model of spectra in backscatter from the cone and cylinders rotating around their axes, which has the singular value problem. Gong YJ et al proposed an analytical model of Doppler power spectra in backscatter from arbitrary rough convex quadric bodies of revolution (whose lateral surface is a quadric) rotating around axes [10]. In exploring the primary sources of turbulent mixing within the atmospheric boundary layer, Manninen et al proposed a method using Doppler LIDAR data, which can detect the presence of turbulence [11].…”

“…The radar echoes of micro-motion targets reveal their intricate details, including structural, electromagnetic scattering, and motion characteristics. For this reason, the identification and detection of targets in space, air, ground, and sea, including ships, is of paramount importance [10,[13][14][15]. In 2008, Victor C. Chen used the method of moments to simulate the precession echo data of the cone cylinder target, and analyzed the characteristics of micro-Doppler components corresponding to the spin and cone components as well as the micro-Doppler components corresponding to each scattering center of the cone [16].…”

“…In the aforementioned study on micro-moving targets, Gong et al [10] rigorously established the correlation between the Doppler shift of rotating targets and their coordinates within the laser band. The micro-motion is also an important form of motion of the target and has a nonnegligible influence on the Doppler power spectrum.…”

In the realm of ballistic target analysis, micro-motion attributes, such as warhead precession, nutation, and decoy oscillations, play a pivotal role. This paper addresses these critical aspects by introducing an advanced analytical model for assessing the Doppler power spectra of convex quadric revolution bodies during precession. Our model is instrumental in calculating the Doppler shifts pertinent to both precession and swing cones. Additionally, it extends to delineate the Doppler power spectra for configurations involving cones and sphere–cone combinations. A key aspect of our study is the exploration of the effects exerted by geometric parameters and observation angles on the Doppler spectra, offering a comparative perspective of various micro-motion forms. The simulations distinctly demonstrate how different micro-motion patterns of a cone influence the Doppler power spectra and underscore the significance of geometric parameters and observational angles in shaping these spectra. This research not only contributes to enhancing LIDAR target identification methodologies but also lays a groundwork for future explorations into complex micro-motions like nutation.

A backscattering model of the average signal power function (SPF) for laser radar 3D range imagery obtained using detector arrays for a complex target with rough surfaces is presented. The model relates the average power at the receiver to the laser pulse, target shape, optical scattering properties of the surface materials, angle of incidence, and other factors. The optical scattering properties of the material are characterized using the bidirectional reflectivity distribution function (BRDF). The effects of the pulse width on the resolution of the 3D range imagery are analyzed. The proposed model can be used to demonstrate 3D laser radar systems and can also be used to generate a library of model data sets for automatic target recognition (ATR) applications.

“…In Ref. [32], when a plane wave was used as an incident laser, the Doppler spectra of rotating convex bodies such as superspheroids, superspheroid cylinders, and their combinations of cylinders and cones have been reported. Based on the above research background, we build a more desired model to further study the Doppler shift characteristics by replacing a plane wave with a pulse beam.…”
