摘　　要：首先给出微多普勒的一般理论模型和弹道目标的微多普勒特征。然后以锥旋调制产生的微多普勒为例,分别研究与微多普勒相关的低频与高频、窄带与宽带、重返时间与照射时间、速度与加速度、相参性和分辨率等六个问题。所得结论对微多普勒的提取和雷达参数的设计具有一定的参考价值。First, the general theoretic model of micro-Doppler and the micro-Doppler signatures of ballistic targets are displayed, and then six problems of micro-Doppler which are low and high carrier frequency, narrow band and wide band, return time and illuminating time, coherence, resolution as well as velocity and acceleration are studied under the case of the micro-Doppler induced by coning. The research results are valuable for the extraction of micro-Doppler and the design of radar parameters.
