基于Radon-Ambiguity变换的机动目标检测方法 首先用基于Radon--Ambiguity变换(RAT)的时频分析方 法估计多个目标的加速度并进行运动补偿,通过频域滤波对多目标进行分离并估计粗略的多普勒 频率(A maneuvering target detection method based on Radon-Ambiguity transform is first used to estimate the acceleration of multiple targets and compensate for motion based on the time-frequency analysis method based on Radon--Ambiguity transform (RAT). The multi-target is separated by frequency domain filtering and the rough Doppler frequency is estimated.)
