Missile-borne penetration attitude calculating device based on combination of geomagnetism and micro-inertia navigation information

Abstract

The invention relates to a missile-borne penetration attitude measuring device, in particular relates to a missile-borne penetration attitude calculating device based on combination of geomagnetism and micro-inertia navigation information, and solves a problem of lack of an attitude calculating device aiming at traditional payload penetration process at present. The missile-borne penetration attitude calculating device based on the combination of geomagnetism and micro-inertia navigation comprises a circuit body (1) and a buffering protective device arranged at the periphery of the circuit body (1), wherein the signal line of the circuit body (1) is led to the outside of the buffering protective device; the circuit body (1) comprises a geomagnetism/micro-inertia navigation measurement combination unit, a missile-borne attitude calculating unit, a missile-borne real time data recording unit, a power supplying and distributing unit and a starting unit; and the geomagnetism/micro-inertia navigation measurement combination unit comprises a signal modulating module, the input end of the signal modulating module is respectively connected with a triaxial gyro sensor and a triaxial geomagnetic sensor, and the output end is connected with an A/D (analog to digital) conversion module. The missile-borne penetration attitude measuring device is reasonable in design and simple in structure.

Description

technical field [0001] The invention relates to a missile-borne penetration attitude measurement device, in particular to a missile-borne penetration attitude calculation device based on the combination of geomagnetic / micro-inertial navigation information. Background technique [0002] A penetrating weapon is a weapon that carries a penetrating warhead and is used to attack targets such as airport runways, ground reinforcement targets, and underground facilities. It is the main weapon for "surgical" strikes against hard targets and their bunkers. For penetrating warheads with complex structures and functions, it is necessary to measure projectile motion parameters in real time during the complex armor-piercing or penetrating process, so as to precisely control the explosion timing of penetrating warheads, obtain the best combat effect, and improve the penetration rate. However, due to the explosion of the first-level warhead during the penetration process, the projectile bod...
