摘　　要：衡量一种军事通信技术优劣的重要指标是其抗干扰性能和隐蔽性,而具备这些优良特性的脉冲无线电技术当前的研究热点是在短距离宽带无线接入中的应用。针对典型的超宽带实现方案脉冲无线电技术进行研究,首先分析了它与传统的直接序列扩频技术的差别,然后着重研究了它的抗干扰性能和抗检测/截获性能,并与DSSS技术进行对比,结果表明脉冲无线电超宽带技术比传统的DSSS技术具有更好的抗干扰性能和隐蔽性,更加适于军事通信应用。Capabilities of anti-jamming and covertness are important measures of military communication technology. Impulse radio technology which has these excellent characteristics has drawn more and more attentions in the study of short-range wideband radio access recently. A research is made on impulse radio UWB （IRUWB）, a typical ultra-wideband （UWB） technology. Firstly, the difference of this technology from traditional direct sequence spread spectrum （DSSS） technology is analyzed. Next, its capabilities of anti-jamming and antidetection/acquistion are studied, and the comparison is done with DSSS technology. As results showed, IRUWB is better than traditional DSSS technology in the capabilities of anti-jamming and covertness, and is more suitable for military communication applications.
