摘要 研究了相位编码准连续波雷达中存在的回波遮挡问题,从波形设计和码型设计两个方面给出了解决方案。在波形设计方面,提出了一种脉内长短码结合的波形设计方法,不仅能够解决近距离回波严重遮挡的问题,而且能对近距离和远距离进行同时探测。在码型设计方面,提出了基于脉间码型捷变的旁瓣抑制方法。理论分析与仿真结果表明,该方法在回波遮挡的情况下仍然具有较好的旁瓣抑制效果,适合于低重频长序列相位编码准连续波雷达。 The eclipse problem of quasi-CW phase-coded radar was analyzed, and solving methods were proposed by waveform and code designs. As for waveform design, a method based on in-pulse combi- nation of long code with short code was put forward, which can solve the severe eclipse problem of short range target, and simultaneously detect the whole range. As for code design, a range sidelobe suppression method based on interpulse code agility was proposed. Theoretical analysis and simulated results show that, the code agility method can work well even when the target echo is eclipsed, so meet the demand of low pulse repetition frequency long code quasi-CW radar.
