Target Tracking System Based on Inertial Stabilized Platform

Article Preview

Abstract:

A target tracking system based on inertial stabilized platform(ISP)is introduced, which can fulfill platform inertial navigation, platform stabilization and target tracking. An IMU is integrated with electro-optical sensors and a laser range finder on a gimbal, which performs attitude transformation by constructing navigation coordinates in a mathematic platform, and the platform inertial information is obtained by transformation matrix between platform and payload coordinates. The inertial platform comprising gyros, electro-optical sensors and servo mechanism is capable of stabilizing line of sight and can be used to track targets in the relevant field of view (FOV). The system can determine geography coordinates of the host platform and target only with inertial information and laser ranging data. The geo-tracking system always locked the target image at the center of FOV by calculating spatial geometry and adjusting LOS attitude. This tracking is different from TV tracking and geo-reference image tracking, which may be influenced by fog and obscurant. When the helicopter is flying over urban or mountain areas for rescue missions, it can avoid the loss of targets due to strong maneuver or LOS obscuration, and reduce the operation load of the aircrew and improve rescue efficiency.
