摘要复杂背景下稳健高效的低可观测目标探测始终是雷达信号处理领域的研究热点和难点。一方面，强杂波背景和目标复杂运动使得信号微弱，时频域难以区分；另一方面，传统雷达体制回波信号资源受限，难以实现对目标信号的精细化描述，亟需发展雷达目标探测新体制和新技术。本文归纳总结了低可观测目标探测面临的技术难点，系统回顾了常用的雷达动目标检测方法，最后从目标探测技术和手段两方面对雷达低可观测目标探测的发展进行展望。

Abstract：To deal with the difficulty in radar signal processing,effective and efficient detection of low-observable targets in complex environments is an ongoing research hotspot.On the one hand,due to strong clutter and complex motion of a target,the signal may be extremely weak such that it is hard to detect the signal either in time domain or in frequency domain.On the other hand,the signal resources of traditional radar are limited and cannot achieve refined description of the target itself.Therefore,it is urgent to develop new system and technology for radar target detection.In this paper,we firstly summarize the main difficulties for low-observable target detection.Then,we systematically review conventional radar moving target detection methods.Finally,we discuss the future development from the perspective of detection techniques and systems.

Key words： signal and information processing radar target detection low-observable target moving target detection multi-dimension information
