军事用途的图象甚低码率传输的研究

Study on Military Image Very-low Code Rate Transmission

针对军事图象的特点采用了离散余弦变换及类RLE编码相结 合的方案，对军事静止图象的传输作了研究。实验结果表明此方案在保持军事目标清晰的前 提下，能达到10倍以上的压缩效果；在波特率为9 600的情况下，可在30s内传输一幅图象， 基本满足实时性要求。

By using the program with combination of the dis crete consine transform and the class RLE coding according to the military image characteristics,the military still image transmission is studied.The experiment has proved that compression effect being ten times more may be obtained on the premise of clearly military target.And one picture can be transmitted in 30s und er the baud rate is 9 600,which is basically meet the real[CD*2]time requirement .
