A dual dynamic target tracking and guidance method based on laser gyroscope

Abstract

The invention discloses a dual dynamic target tracking and guidance method based on laser gyroscopes, including step 1: obtaining the GPS coordinate T of the target under the dynamic platform in real time G , the real-time GPS coordinates of the tracking system A G , the real-time pose of the platform (α, β, γ), the initial pose (α 0 ,β 0 ,γ 0 ); Step 2: convert the ground-fixed coordinates of the target into the coordinates of the moving platform of the target, step 3: convert the calibration horizon system and the tracking system axis system, determine the conversion relationship between the tracking system axis system and the horizon system where the tracking system is located, Obtain the conversion angle from the horizon system to the axis system of the tracking system; Step 4: Fix the inertial laser gyroscope on any position of the platform, and the tracking system is installed on the platform, and the zero point of the encoder will not be adjusted after installation, just After completing one calibration, in the subsequent dynamic platform application, if the relative installation position does not change, it can be directly applied. To meet the needs of moving target tracking and guidance on the dynamic platform, a dual dynamic target tracking and guidance algorithm is studied.

Description

technical field [0001] The invention relates to the technical field of target tracking, in particular to a laser gyroscope-based dual dynamic target tracking and guidance method. Background technique [0002] Target tracking guidance refers to the process of introducing dynamic flying targets in the air into the field of view of the photoelectric tracking system. The acquisition, tracking, and aiming of photoelectric targets are all carried out on the premise of guiding the target into the tracking field of view. Dual dynamic means that in addition to the dynamic flight of the target, the position and attitude of the platform where the tracking system itself is located also undergoes real-time dynamic changes. In this case, to achieve real-time guidance to the target, in addition to determining the position of the target in the air in real time, it is also necessary to grasp the position and attitude changes of the tracking system platform in real time. The dynamic target ...
