During explosive detonation or air blast experiments, long cables are commonly used for transmitting signals delivered by pressure sensors to the safe place of the acquisition unit. While constant efforts are undertaken for enlarging the bandwidth of sensors in order to improve the measurement precision of the peak pressure, the limitations of the wired transmission of blast pressure signals delivered by these sensors are not addressed. We discuss here such limitations and propose a wireless new solution for the dynamic measurement of Friedlander‐type signals delivered by ultra‐wideband sensors (>
). Contrary to the wired solution, the distance between the sensor and the acquisition unit does not limit the measurement bandwidth of the wireless setup. Experimental results are reported for validation purposes and pave the way of the dynamic measurement of blast pressure variations occurring at the heart of the fireball generated during explosions.

弗里德兰德型信号的无线传输，用于动态测量爆炸压力
在爆炸或爆炸实验中，通常使用长电缆将压力传感器传递的信号传输到采集单元的安全位置。尽管为了提高峰值压力的测量精度而不断努力以扩大传感器的带宽，但是并未解决由这些传感器传递的爆炸压力信号的有线传输的局限性。我们在这里讨论这些局限性，并为无线测量超宽带传感器（>
）。与有线解决方案相反，传感器与采集单元之间的距离不限制无线设置的测量带宽。报告了实验结果用于验证目的，为动态测量爆炸过程中在火球中心产生的爆炸压力变化铺平了道路。
