摘　　要：基于诱导脉冲的雷达组合波型可以在保证雷达有限的探测能力前提下,有效对抗典型的侦察设备的截获,不易测出有用信号的载频,不易进行分选和识别,是典型的雷达低截获波形。文章分析了这种组合波型的构成原理、抗侦察设备截获能力,并给出了仿真、验证的数据,得出了结论,具有重要的参考价值。Combination radar waveforms based on cheating pulse can effectively confront the interception of a typi- cal reconnaissance receiver, but it is difficult to measure their signal frequency, sort out and recognize pulse series under the preconditions of guaranteeing the limited detection ability of the radar; these waveforms are typical LPI radar waveforms. Sections 1 through 4 of the full paper explain the exploration mentioned in the title, which we be- lieve is new and indicates that we have succeeded in obtaining better results than those obtainable with existing methods. These sections are respectively entitled： the combination waveform based on cheating pulse; the perform- ance of the cheating pulse for resisting the channel receiver; the performance of digital radar frequency memory technology; the performance of resisting the sorting out and recognition. We simulate respectively the sorting - out resistance and the digital radar frequency memory of the combination waveforms; the simulation results, given in Figs. 10 through 15, and their analysis show preliminarily that the combination waveform based on cheating pulse is indeed a good type of LPI waveform, thus indicating that we have succeeded in obtaining better results than those obtainable with existing methods.
