摘要翻译：
随机脉冲重复间隔(PRI)波形由于能有效地降低距离模糊和多普勒模糊，提高电子对抗能力而引起了现代雷达领域的广泛关注。本文推导了模糊函数(AF)统计特性的理论结果，表明通过增加脉冲数目和PRI抖动范围，可以有效地抑制距离模糊和多普勒模糊。这为波形设计提供了重要的指导。PRI随机化引起的旁瓣基座显著抬升会降低弱目标检测的性能。在此基础上，我们提出采用正交匹配追踪(OMP)来克服这一问题。仿真结果表明，OMP方法能有效降低强目标旁瓣基座，提高弱目标估计性能。

英文摘要：
  Random pulse repetition interval (PRI) waveform arouses great interests in the field of modern radars due to its ability to alleviate range and Doppler ambiguities as well as enhance electronic counter-countermeasures (ECCM) capabilities. Theoretical results pertaining to the statistical characteristics of ambiguity function (AF) are derived in this work, indicating that the range and Doppler ambiguities can be effectively suppressed by increasing the number of pulses and the range of PRI jitters. This provides an important guidance in terms of waveform design. As is well known, the significantly lifted sidelobe pedestal induced by PRI randomization will degrade the performance of weak target detection. Proceeding from that, we propose to employ orthogonal matching pursuit (OMP) to overcome this issue. Simulation results demonstrate that the OMP method can effectively lower the sidelobe pedestal of strong target and improve the performance of weak target estimation.
