一种通用小型弹载图像遥测设备设计

Design of a universal small missile-borne image telemetry equipment

摘要:

弹载遥测设备是导弹研制阶段的重要参数测量设备，中小型导弹通常给遥测设备可使用空间比较狭小。目前，国内某小型导弹遥测设备指标提出了10 Mbps码率、能支持红外图像传输以及支持波道表在线可编程的要求，传统遥测产品的设计方案无法解决遥测设备体积小和功能全的突出矛盾。利用软件无线电的设计思想，采用AD9361和FPGA的硬件架构，使用了软件在线可编程技术、GMSK先进调制技术、基于FPGA的JPEG2000图像压缩技术和对称赋形天线技术，实现了一款集成度高、可靠性好、通用经济的先进弹载图像遥测设备。通过测试试验表明，弹载遥测设备简化了以往复杂的硬件设计，有效降低了弹载遥测设备的体积、重量和功耗，高集成度提高了产品可靠性，而且具备可重构能力，提高了弹载遥测设备的通用性和试验效率，有利于降低研发成本。

Abstract:

The missile-borne telemetry equipment is an important parameter measurement equipment in the missile development stage, small and medium-sized missiles usually have a relatively small space for telemetry equipment. A certain domestic small missile telemetry equipment index puts forward the requirement of 10 Mbps bit rate, which can support infrared image transmission and support the online programming of the channel table. The design scheme of traditional telemetry products cannot solve the prominent contradiction between the small size and full functions of telemetry equipment. Utilize the design idea of software radio, adopting AD9361 and FPGA hardware architecture, using software online programmable technology, GMSK advanced modulation technology, FPGA-based JPEG2000 image compression technology, symmetrical shaped antenna technology to achieve a high integration, good reliability, general economy advanced missile-borne image telemetry equipment. Tests show that the missile-borne telemetry equipment simplifies the complex hardware design in the past, effectively reduce the size, weight and power consumption of missile-borne telemetry equipment, the high level of integration improves the reliability of products, and has the ability to reconfigure, which improves the versatility and test efficiency of missile-borne telemetry equipment, which is conducive to reducing research and development costs.
