Research On Striking Of Long-distance Evaluation System Based On Wireless Sensor Network

Precision striking of long-distance firepower has played a vital role in the modern informational war. The inertial guided trajectory missile, which belongs to the so-called leave it alone after launching out weapon, has been greatly applied in the long-distance firepower system. Missile hitting situation and striking effect test are generally investigated in the target area by the scouting aeroplanes and UAVs. However, these means are not reliable for their high cost, great risk and long cycle, and can not be conducive to fit the rapidly-changing informational war battlefield. If the information feedback time of striking effect is shortened, the commander could make next decisions quickly which can improve much higher combat efficiency and obtain greater battling success.Actually, the designed system in this thesis is a wireless sensor network system, which is based on Beidou navigation system to accomplish location and information transmission, and could feedback target damage data instantly. The system can collect the damage data by the wireless sensor node dispersed in the target area along with the missile and transmitted it to the background. Based on the analysis of data, the missile hit rate and expected damage effect can be acquired. In this way, our military commanders can grasp accurate target informations without delay, make responses, judgments and next decisions quickly on the battlefield with instantaneous changes, which could promote war situation developing with a more favorable direction.The development and application situations of wireless sensor network and Beidou satellite navigation system in military field are introduced in this thesis firstly, and the key technologies of new construction and function system have been put forward. Based on preview studies, the design scheme of long-distance fire hit which is built on the Beidou navigation system and WSN is investigated emphatically. Through the need for adapting to serious situation on the battlefield, the precise positioning algorithm combing with Beidou navigation system and WSN, the reliable routing algorithm with a guaranteed quality of service (Qos) are designed respectively, as well as the communication protocol between two sides, the nodes and nodes, the nodes and the satellite inside the WSN networks. Based on this, this thesis has completed the overall design of the system, and simulated the corresponding function modules.25figures,31references.
