Description

technical field [0001] The invention belongs to the technical field of ultra-high-speed target imaging and attitude calculation, and in particular relates to an ultra-high-speed moving target attitude measurement system and method. Background technique [0002] Ultra-high-speed moving target attitude measurement technology is the product of the combination of traditional imaging tracking technology and modern laser irradiation technology. It is an attitude measurement system technology for moving targets from low speed to high speed and then to ultra-high speed. Modern weapons and equipment are developing rapidly, and are constantly developing in the direction of ultra-high-speed, long-distance, and high-precision strikes. For example, ultra-high-speed kinetic energy is large, and the running speed is fast. The speed can reach several Mach or even more than ten Mach, and imaging is difficult; The separation attitude and stability of the weapon system will seriously affect th...

Problems solved by technology

[0003] The traditional method of measuring the attitude of a moving target is mainly to use the sensor carried by the target to monitor the instantaneous running state of the target, and then calculate the moving attitude of the target. A carrier attitude measurement method and system, the system uses a three-axis acceleration sensor, a three-axis magnetometer and a three-axis rate gyroscope to measure the components of the acceleration of gravity, the magnetic induction intensity and the angular velocity of the carrier on the three axes of the carrier coordinate system respectively, but the When the system is working, multiple sensors must be arranged on the moving carrier, which is an active measurement and does not meet the attitude measurement requirements of ultra-high-speed flying targets that cannot carry measurement devices.
