Range migration is an inevitable problem when detecting moving targets. Especially, for the high-speed targets, the measurements will be ambiguous in Doppler, which further complicates this problem. Range migration is the result of the well-known range-Doppler coupling. The range-Doppler coupling can be also regarded as the coupling between the range and velocity. By using the reversal operation in the slow time and fast frequency domain, a signal with the opposite characteristic of the range-velocity coupling can be obtained to counteract the range-velocity coupling in the echo signal, which allows the energy of the target can be accumulated in the same range-Doppler cell. Compared with other existing methods for high-speed target detection, the proposed method shows its advantages in the simplicity of implementation and computational efficiency. Experiments based on simulated data and real data are carried out to assess the performance of the proposed method.

在检测运动目标时，范围迁移是不可避免的问题。特别是对于高速目标，在多普勒测量中将是模棱两可的，这使这个问题更加复杂。距离迁移是众所周知的距离多普勒耦合的结果。距离多普勒耦合也可以看作是距离与速度之间的耦合。通过在慢时频域和快频域中使用反向操作，可以获得具有距离-速度耦合相反特性的信号，以抵消回波信号中的距离-速度耦合，这可以使目标的能量为累积在同一距离多普勒单元中 与其他现有的高速目标检测方法相比，该方法具有实现简单，计算效率高的优点。
