Abstract

The wobble performance of cone-shaped target with its micro-Doppler signature is researched in this paper.After the interrelated concepts and signal model of micro-Doppler are introduced

the wobble model of cone-shaped target is built

and the theoretical formula of its micro-Doppler is derived separately with the algebra and matrix methods.By the simulation

the micro-Doppler modulation induced by wobble is extracted successfully from the radar echo with time-frequency analysis method

which agrees well with the computing result

and suggests that the wobble model of cone-shaped target and the mathematical derivation of its micro-Doppler theoretical formula are valid.Besides

the influence of velocity and acceleration on micro-Doppler is researched as well as the request of micro-Doppler on the radar return time and illuminating time

and the research results are valuable for the extraction of micro-Doppler.
