复杂背景下远距离合作信标识别与定位

传统的飞行器合作信标测控中，以常规光源作为信标，不具备复杂环境的适应能力，尤其存在主动干扰源的情况，如何准确识信标是电视跟踪与测控领域的重点研究内容。本文对信标设计与识别定位方法进行研究，采用激光光源作为合作信标，设计可调制驱动电路，将信息编码调制技术应用在调制光源中，实现了可调制合作信标；并设计了调制与成像解调耦合的处理算法，可有效区分干扰目标与真实目标。试验结果表明，本文设计的可调制信标满足需求，调制与解调处理算法可实现合作信标的精确识别与定位，具备抗干扰能力。

Identification and localization of Beacons in Long-distance and Complex Background Conditions

For traditional aircraft cooperative beacon measurement, ordinary light is used as the beacon which does not have the adaptability to fit complex environment, especially in the case of active interference. How to identify the becon accurately has become a key research issue in the field of television tracking and measurement. This paper investigates the beacon design, identification and positioning methods, uses the laser light as the cooperative beacon, designs the adjustable driving circuit, applies the information coding modulation technology to the modulated light, and realizes the adjustable cooperative beacon. And the coupling imaging demodulation algorithm of the modulation is designed which can effectively distinguish interference target and the real target. The experiments show that the modulated beacon designed in this paper meets the requirements, and the modulation and demodulation algorithm can identify and position the cooperative beacons accurately and has the ability of anti-interference.
