摘要

针对脉间相位编码波形带来的多普勒维旁瓣抬高的问题,提出一种基于clean思想的旁瓣抑制方法。首先通过脉间多普勒处理在频域聚焦目标能量,然后加窗截断目标位置后变换至时域完成目标信号重构,最后通过构造不同编码信号完成旁瓣抑制。所提方法可以有效解决脉间相位编码导致旁瓣抬高影响弱小目标检测的问题,仿真验证了方法有效性。

Abstract

To solve the problem of Doppler side lobe elevation caused by inter pulse phase coded waveform, a side lobe suppression method based on clean idea is proposed. Firstly, the target energy is focused in the frequency domain by inter pulse Doppler processing, then the target position is truncated by windowing and then transformed to the time domain to complete the target signal reconstruction. Finally, the side lobe suppression is completed by constructing different coded signals. The proposed method can effectively solve the problem that the side lobe elevation caused by inter pulse phase coding affects the detection of small and weak targets. Simulation results show the effectiveness of the method. This method has practical significance for UAV anti-collision system.

Key words： inter pulse phase coding; side lobe suppression; doppler domain; time frequency conversion
