Integrated Design and Implementation of Shipbornetelemetry and infrared TV tracking

摘要:

针对遥测近海面测量时面临的复杂场景干扰以及视觉观感不强等方面的问题，提出在舰载遥测系统上加装红外跟踪系统。采用口径140 mm、焦距260 mm/520 mm的光学系统，能对红外源目标进行跟踪、图像记录和在本地/远程实时监控等功能。提出的Kalman滤波估计算法，能够准确预测目标的速度，使得速度顺馈技术在设备中成功实现。介绍了舰载遥测系统的特点以及一体化设计思想，实现了对遥测系统远、近场电轴的标校以及遥测与红外的互跟踪，并通过实例验证了设计的可行性。

Abstract:

The design of infrared TV tracking equipment installation on shipborne telemetry system is proposed to solve the weak visual image problem and the near sea surface measure problem of the telemetry system when face the complicated background interference. Firstly, the feature of shipborne telemetry system and the integrated design are introduced, which realize the telemetry system calibration in near and far field, and switch freely between telemetry and infrared tracking. The infrared TV tracking equipment adopts the optics system with 140mm caliber, 260mm/520mm focus, which can track the infrared object, record image and be monitored. Then the Kalman filter arithmetic is designed to predict the object speed accurately, which successfully fulfills the speed forward feed technique on the equipment. Finally the design feasibility is validated by experiments.
