摘要
空中爆炸冲击波的实测信号中,常有幅值很大的瞬时干扰信号,冲击波超压峰值的获取往往需要采用后期信号处理的方法。针对模爆器产生的爆炸冲击波超压的特点,采用"经验拟合"和"数字滤波"2种不同的处理方法进行信号的消噪处理,通过对试验测试结果的比较研究,肯定了传统的经验公式拟合方法在爆炸冲击波信号处理中的适用性。
In the air blasting shock wave effects research, transient signals with large peak values may be of some influence to the blasting shock wave measurement, signal processing method is often used to acquire the true value of blasting shock wave overpressure. By analyzing the character of signal generated by the nuclear blast load generator, it adopts two different methods, the empirical formula fitting and digital filtering for eliminating noises. It confirms that the empirical, formula fitting is applicable for signal processing of explosive shock wave.
