基于时间分段数据的弹道目标微多普勒时频分析方法
Analysis of micro-Doppler time-frequency for ballistic targets based on time slicing data
摘要
Abstract
As the anti-missile radar is required for keeping the tracking to those multiple targets, simultane-ously rather than the longer for continuously observing the same one target, this paper presents a method for time-frequency analysis based on time slicing data. In this scheme, the ideal time signals are not directly got, while the correlation function of the ideal time signals is acquired by integrating the bilinear interpolation and AR estimation, and the time-frequency graph is obtained by using the WVD method. Simulation results indicate that the proposed method’s precision is higher that the time-domain linear interpolation method’s.关键词
