摘要
微型飞行器(microaerialvehicles,简称MAVs)有限的带载荷能力对其上的侦察设备提出了更高的要求。该文重点研究了应用于微型飞行器的微小摄像与无线传输系统。该系统以低质量和小体积实现了一定距离内视频图像的无线传输。系统组成包括机载摄像、发射单元和地面接收单元。机载摄像发射模块质量为16g(包含摄像头和发射天线),体积为30mm×40mm×5mm,可实时传输视频图像,传输有效半径达1km(视距范围内)。该系统成功地应用在翼展320mm的飞行器中。
This paper presents a microphotography and wireless transmission system for use in micro aerial vehicles (MAVs). The surveillance devices in MAVs must be carefully designed because of their quite limited payload capability. The developed system is small and lightweight but with high performance. This paper describes the system components in the microphotography unit, the radio frequency unit and the reception station. The parts in the MAVs weigh 16 g (including the camera and the antenna) with a size of 30 mm×40 mm×5 mm. The system can transmit and receive real-time video and has a practicable distance of 1 km (line of sight). The system provides a reliable, light microphotography, and wireless transmission system for MAVs with 320 mm wingspan.
