论文摘要
为了缓解脉冲雷达中的范围多普勒旁虫引起的干扰，我们提出了一种基于戈莱代码的多普勒弹性互补波形的新方法。我们设计了发射脉冲序列和接收脉冲重量，以便最大化脉冲权重和给定的窗口函数之间的相似性，并满足多普勒空点和能量的约束。总结为一个双向分区问题，然后通过半限定编程和随机化技术解决。因此，因此获得的新型波形在多个且可调的多普勒区域中完全抑制了其范围的旁路，并且在多普勒侧lobe抑制，多普勒分辨率和SNR中表现良好。它在发现存在密集干扰的情况下检测略微移动的弱目标方面表现出了巨大的希望。
To relieve the interference caused by range-Doppler sidelobes in pulsed radars, we propose a new method to construct Doppler resilient complementary waveforms based on Golay codes. We design both the transmit pulse train and the receive pulse weights, so that the similarity between the pulse weights and a given window function is maximized and the constraints on Doppler null points and energy are met. That is summarized as a two-way partitioning problem, and then solved by semidefinite programming and randomization techniques. The novel waveform thus obtained has its range sidelobe outright suppressed in multiple and flexibly-adjustable Doppler zones, and performs well in Doppler sidelobe suppression, Doppler resolution and SNR. It shows great promise in detecting slightly-moving weak targets with the existence of dense interference.
