| 摘 要： | 提出了一种基于谱熵的火箭弹开舱点测量方法,当火箭弹开舱时,雷达反射截面积(RCS)、多普勒频率突变引起谱熵突变,从而检测开舱点.该方法充分利用了RCS、多普勒突变信息,避免了单独利用RCS、多普勒突变信息带来的局限,解决了相参积累时间短,频域分不开时的开舱点检测问题.实验结果表明,该方法能较精确地测量开舱点.

| Abstract: | In this paper,a new approach to detect open bin time is proposed. Based on spectral entropy,open bin time is detected through mutation information of spectral entropy as a result of RCS and Doppler frequency. This method makes use of mutation information of RCS and Doppler frequency fully,avoids the limitation of single RCS or single Doppler frequency,and solves the measurement problem of rocket open bin time because of short coherent time integration. Experiment results indicate that this method can detect... |
