摘要:

间歇收发导致真实距离像产生虚假峰,在多目标场景下,真假距离像会发生重叠,从而影响目标的信息获取。针对这一问题,提出基于匹配滤波器联合设计的室内场目标特性测量方法。首先建立目标微动模型,分析脉冲信号的间歇收发回波特征。然后利用非匹配滤波器的输出特性,对目标距离?慢时间序列中的虚假距离像进行抑制,基于剔除后的真实距离像序列设计了微动特征提取流程。仿真验证结果表明,在多目标场景下,所提方法能够恢复目标的真实距离像,且间歇收发回波得到的微多普勒分布与理论结果保持一致,对暗室中利用脉冲信号进行目标特性测量、分析目标动态散射特性,具有一定的实际应用价值。

Abstract:

Interrupted transmitting and receiving (ITR) can cause false peaks in range profiles, and when the ITR of the pulse signal is conducted, the real and false peaks in the range profile may be overlapped for wideband signal. To solve this problem, a joint ITR and matched filter design method focusing on measuring the characteristics of target is proposed. First, the ITR echo characteristics of the pulse signal are discussed based on the micro-motion echo modeling of ballistic target. Then, the real range profile of target can be obtained by using the output characteristics of the unmatched filter, and the whole process of micro-motion feature extraction for rotating target is proposed. The simulation verification results show that in multi-target scenarios, the proposed method can restore the true range profile of the target, and the micro Doppler distribution obtained by intermittent echo transmission and reception is consistent with the theoretical results. The use of pulse signals for target characteristic measurement and analysis of dynamic scattering characteristics in darkrooms has certain practical application value.

Key words: interrupted transmitting and receiving (ITR), segmented pulse compression, micro-motion, range profile
