Abstract

Abstract

A new method is proposed to estimate micro-motion parameters of space precession targets. Based on the micro-Doppler characteristic of a precession target, the Fourier transformation is applied to estimate precession parameters roughly. Then based on the time-frequency spectrum characteristic of the echo signal, coherent accumulation is applied to obtain a 3-D high resolution distribution of the target. The estimation accuracy of the parameters is refined by calculating the whole image entropy. Simulations results confirm the effectiveness of our proposed method.
