Loitering Missile Environment Information analysis and application in Fuze S&A

Abstract

As a new kind of ammunition on the battlefield in recent years, airborne loitering missile is widely used to carry out various combat tasks and has attracted extensive attention from all countries in the world. Based on the campaign mode of the airborne loitering missile, there is no strong inertial force during its launching and flight, so the fuze S&A cannot rely on the strong inertial force. In this paper, identification and processing methods are designed for the weak environment information, which includes aerodynamic and attitude information. In the launching stage, the variations of missile’s aerodynamic and attitude angle are large and frequent. In contrast, the variations are slight and stable in the straight-level flight stage. Based on MEMS sensors and the missile guidance and controlling system, the difference of the weak environment information between the two adjacent stages can be obtained. Based on this difference, the loitering missile can distinguish whether it is in the straight-level flight stage, and it can be used as the typical feature for the missile fuze S&A arming. Due to the MEMS sensors and processing circiuts, the volume of fuze S&A will be smaller and the safety distance between the launching aircraft will also be extended by this method.
