摘　　要：红外图像传输的速率可高达十几Mbps,现有的设备不能解决低带宽导致传输误码率高的问题。设计了一种融合图像数据压缩、信道交织编码和数字MSK调制技术的图像遥测传输系统,解决了以现有低带宽设备实现高速率传输的问题。通过采用Xilinx公司的Spartan3E系列FPGA XC3S500E作为数据采集控制器,以ARM(S3C2440A)实现图像算法处理器,构建PCM/FM遥测系统硬件平台。最后在硬件平台上验证系统性能,通过测试系统传输误码率证明了方案的可行性。The transmission rate of infrared photo is up to ten Mbps, which is very hig, existing equipment can not solve the problem of low bandwidth leads to transmission high error rate.This paper designed a remote sensing image transmission system, which is mixed image data compression and channel coding and the digital MSK modulation tech- nique, solved the problem of low bandwidth available equipment for high rate transmission.This paper used Xilinx cor- poration Spartan3E XC3S500E series FPGA as the data acquisition controller, and ARM （S3C2440A） as the image processing algorithm controller, to construct of PCM/FM telemetry system hardware platform.Finally, it verified the system performance on the hardware platform, Transmission error rate by test system proved the feasibility of the scheme.
