基于DSP的侵彻引信计层/计空穴系统设计

Design of Layer-Count/Void-Count Penetration Fuze System Based on DSP

现代化战争主要是依靠信息化、战略化和技术化作战,而如何彻底摧毁敌军基地、战斗总部及高价值硬目标是当代战争的必然趋势.针对侵彻武器对引信精确炸点控制技术的需求,提出了一种侵彻引信计层/计空穴系统的电路实现方法,首先对加速度传感器获得的信号进行自相关、低通滤波和放大等预处理,然后以数字信号处理器(DSP)芯片作为核心处理器,采用阈值算法实现引信的计层/计空穴功能.测试结果表明,该方法用于侵彻引信的计层/计空穴控制具有可行性.

The fight mainly relies on informatization, strategy and technicalization in modern war, and how to destroy the enemy base, combat headquarters and high value hard target is an inevitable trend. Aiming at the requirement of penetration weapon for fuze accurate point-of-burst control technology, a circuit implement method of layer-count/void-count system for penetration fuze was put forward. Firstly, the preprocess circuits, including self-correlation, lowpass filetering and amplification, were designed based on the acceleration sensor signals. Then, taking the digital signal processor （DSP） chip as the core processor, the fuze layer-count/void-count function was realized by employing the threshold algorithm. The test results indicate that the method has feasibility for the layer-count/void-count control of penetration fuze.
