Hard Target Identification Technology And Circuit Design

With the continuous developments of technology and deeply applications in military,the military strength of both sides in warfare is growing in modern war. The methods ofassault are constantly updated, and the important military targets have also been solidity andundergrounded. The development of penetration technology and burrow weapons has beenput forward higher requirements. There are mainly four kinds of methods to control theinitiation of hard target penetration ammunition accurate damage: timing blasting, void/layeridentification initiation, depth initiation, medium recognition initiation. Of which the methodof layer identification means that when the target is hard multi-target, fuze circuit isacquisitioned and processed the signal transmission from high-g acceleration sensors,thencalculated the penetrated layers of the penetration warhead, In order to the control thewarhead detonation in the intended target layer. The possibility of interference generates andthe reasons their cause is discussed in this design. The performance of Anti-jamming isresearched when adopting layer identification initiation. Technical support is provided in thispaper for the development of the penetration fuze.Anti-jamming capacity is mainly researched when adopting layer identification initiationin this paper. In order to control of the burst point precisely. Firstly, the causes of interferencemay be produced is discussed, the interference layer and bimodal interference are determinedthe two main forms of interference. Then, Anti-jamming system was established the modelaccording to the characteristics of the interferences’ produce. Establishing module in theMATLAB SIMULINK, which using analog signals of redacting, jamming system aresimulated based on the algorithm, the result is theoretically possible. In order to overcome thetime delay may caused in process of signal acquisition when use traditional way of using DSPand MCU control core. A set of pure hardware circuit was designed in this paper, which realizing the function of anti-interference. Then make PCB to debugging circuit.The test results: This design verifies the feasibility and accuracy of the anti-jamming.Avoiding the counter error when facing interference layer and bimodal interfere. Burst pointis controlled precisely.
