利用信号传播过程中能量衰减的规律,测量了发射信号反射的回波信号与原发射信号的能量变化,设计了计行程硬目标侵彻弹丸的碰撞速度测量系统。经公式推导后得出能量衰减率与速度的关系表达式,由此确定出需要测量的量,并设计出对应的测距模块、信号接收模块和场强测量模块。最后通过处理器进行数据处理得到了弹丸碰撞初速度。
Using the energy attenuation law in the process of signal propagation, the energy changes of the reflected echo signal and the original transmitted signal of the transmitted signal were measured, and the collision speed measuring system of the hard target penetrating projectile was designed. After deducing the formula, the relation between the energy decay rate and the speed is deduced to determine the quantity to be measured and design the corresponding ranging module, signal receiving module and field strength measuring module. Finally, the data processing by the processor projectile collision initial velocity.
