中文摘要：

介绍了一种随机噪声超宽带雷达信号，给出了这种信号的功率谱形式。通过理论分析和计算机仿真，研究了这种信号相关接收压缩波形的统计旁瓣电平以及目标的分辨能力。仿真结果表明，这种信号与线性调频超宽带雷达信号相比，在一定的条件下，可以获得更低的峰值旁瓣电平，并且具有更好的分辨能力。

英文摘要：

The random noise uhra-wideband radar signal was analyzed and its power spectral function was also given. Through the theoretical analysis and computer simulation, the statistical peak sidelobe level （PSL） of compression wave of the correlation receiver, and the resolved ability were studied. The simulation result shows that this signal possesses lower PSL better resolved ability in comparison with the LFM ultra-wideband radar signal on a certain condition.
