针对引信共线装定过程中分布电容影响装定可靠性的问题
建立基于装定器模块、能量与信息传输模块、引信电路模块的等效电路模型。分别研究在装定输出信号为高电平时和低电平时两种情况下
分布电容对共线装定系统信息传输特性的影响。得出高电平时分布电容对共线装定系统影响较小的结论
并推导低电平时引信识别到的接收信号的低电平脉宽与分布电容的关系式。提出两种优化方法
一种利用二极管屏蔽外部因素如并入电缆引入的电容;另一种利用并联一个阻值较小电阻的方法来降低系统的时间常数
从而提高引信识别到的低电平脉宽
提高装定可靠性。经仿真和实验验证
两种方法均提高了引信识别接收信号的可靠性。
An equivalent circuit model based on the setter module
the energy and information transmission module and the fuze circuit module is established for the effect of distributed capacitance on the setting reliability in the process of fuze collinear setting. The influences of distributed capacitance on the information transmission characteristics of collinear setting systemwhen the setting output signal is at high level and low level are studied
respectively. The conclusion is drawn that the distributed capacitance has little influence on the collinear installation system at high level
and the relationship between the low-level pulse width of the received signal recognized by the fuze and the distributed capacitance at low level is deduced. Finally
two optimization methods are proposed
one uses a diode to shield the external factors
such as the capacitance introduced by the incorporated cable
and the other uses a parallel-connected resistor with a smaller resistance to reduce the time constant of the system
thereby improving the recognition rate of the fuze. The low-level pulse width improves the reliability of fuze setting. The simulation and experimental verification show that both methods improve the reliability of the fuze to identify the received signal.

To solve this problem, different from the traditional method, a state-of-the-art detection method based on density-distance space is proposed to apply to the trajectory correction fuze. First, parameters of the infrared image sensor on the fuze are calculated to set the boundary limitations for the target detection method. Second, the density-distance space method is proposed to detect the candidate targets. Finally, the adaptive pixel growth (APG) algorithm is used to suppress the clutter so as to detect the real targets. Three experiments, including equivalent detection, simulation and hardware-in-loop, were implemented to verify the effectiveness of this method. Results illustrated that the infrared image sensor on the fuze has a stable field of view under rotation of the projectile, and could clearly observe the infrared small target. The proposed method has superior anti-noise, different size target detection, multi-target detection and various clutter suppression capability. Compared with six novel algorithms, our algorithm shows a perfect detection performance and acceptable time consumption.
