内弹道多普勒信号处理方法目前主要有Hilbert变换及时频分析,针对Hilbert变换处理内弹道运动参数计算过程复杂、运算量大的不足,文中提出基于时频分析的内弹道多普勒信号处理方法,设计内弹道模拟试验装置进行测试,结果表明,时频分析程序实现简洁、速度快、效率高,位移精度与Hilbert处理结果相当,两种方法成功应用于火炮内弹道运动参数测量中。

The Doppler signal of the projectile in-bore longitudinal movement was processed with the Hilbert transform and time-frequency analysis at present. Concerning the problem that the Hilbert transform has large amount of calculation and complexity in evaluating interior ballistic parameters, it is proposed to process interior ballistic Doppler signal based on time-frequency analysis, the test facility is made for interior ballistic simulation test, the result shows that time-frequency analysis is concise, fast and efficient, the accuracy of displacement is equal to the Hilbert result.
