为了研究弹引系统的动态特性参数，在反弹道测试技术的基础上，发展了一种新的动态着靶模拟测试技术：碰前接电技术。设计加工了实验弹及弹上接电装置；根据原理性实验，求出信号建立时间，据此设计了靶前接电装置，进而组成了碰前接电技术测试系统；将此系统用于靶场实验，获得了在实际载荷下雷管部位的冲击加速度响应曲线；对加速度曲线进行最大熵谱估计，确定了测得的信号是完整的；利用小波变换消除噪声，提取特征频率重构了加速度曲线。
In order to study the dynamic characteristic parameters of the missile guidance system, a new dynamic target simulation test technique is developed based on the anti-ballistic test technique: the pre-touch power-on technique. According to the principle experiment, the signal establishment time is obtained, and the target front electric equipment is designed, and then the test system of the front contact electric power is formed. The system is used in the shooting range Experiments were carried out to obtain the impact acceleration response curve of the detonator under the actual load. The maximum entropy spectrum of the acceleration curve was estimated to determine the signal integrity. The wavelet transform was used to eliminate the noise and extract the characteristic frequency to reconstruct the acceleration curve.
