- Abstract
The article considers the problem of mathematical modeling of Microdopler signals reflected from small-sized aerial objects such as unmanned aerial vehicles and biological targets. A phase-coherent mathematical model of the reflected radar signal has been developed based on the representation of the target as a set of distributed scattering elements with rigid and articulated kinematics. It is shown that the difference in the physical nature of the micro-movements of the target elements leads to a fundamentally different phase structure of the Microdopler components with similar energy characteristics of the spectrum. Based on the analysis of the phase properties of the reflected signals, the use of the phase coherence coefficient as a distinguishing feature for radar recognition of small- sized aerial objects in conditions of a low signal-to-noise ratio is theoretically justified
