中文摘要：

建立＂人在回路＂制导链路模型,便于后续研究数据链的抗干扰性能及寻求破坏制导链路通信的方法。对单帧黑白图像,采用以CDF9/7小波滤波器和优化截断嵌入块编码（EBCOT）为核心的JPEG2000图像压缩标准,来模拟传输的连续视频图像帧,建立了基于直序扩频以及键控频移通信体制的双向信息传输通道。用MATLAB编程实现了仿真,并从干扰容限和误码率的角度对数据链的抗干扰性能进行了分析。通过分析建立了简单而抗干扰的信息传输链路。

英文摘要：

A guidance link with man in the loop model is established to study the anti-jamming performance of data link and seek the jamming methods.For the single-frame black-and-white image,JPEG2000 image compression standard with CDF 9/7 wavelet filter and EBCOT coding as its core,is adopted to simulate the transfer of continuous video frame,and the DS-MSK communication system-based bidirectional information transmission channel is set up.Simulations with MATLAB are done,and then the anti-jamming performance of the data link are analyzed from the aspects of jamming margin and BER （bit error ratio）,and a simple and anti-jamming information transmission link is established.
