The paper presents an approach to modeling of a range-Doppler image of a multicopter, formed in a radar with a wide-band continuous signal. A feature of the approach is taking into account the observation angle, spatial orientation and the current angle of rotation of each of the multicopter propellers, based on wide-band all-angle estimates of their complex-valued reflection coefficients on horizontally and vertically polarized signals, formed using the microwave devices CAE system. The results of simulation of the range-Doppler image of the DJI Phantom 4 multicopter propeller system based on the actual recording of its flight parameters loggeded with the onboard autopilot are presented. Using the proposed model it was defined that the feature of range-Doppler images formed with wide-band continuous radar is the components frequency shifting not only on the Doppler frequency coordinate, but the slant detection range coordinate too.
