N2 - In the over-the-horizon radar (OTHR), the coherent integration time can approach to tens of seconds. In such a long coherent integration time, the effects of across range unit and across Doppler unit of uncooperative targets may become obvious, which will cause SNR loss for traditional moving target detection methods like MTD. In this paper the second-order generalized Radon-Fourier transform (GRFT) is introduced for detection for OTHR highly maneuvering target, which can accumulate energy along all possible target trajectories after phase compensation to obtain the improvement of detection probability. Based on OTHR highly maneuvering target modeling and analysis, it is showed that the second-order GRFT can outperform the exiting MTD with more than 20dB SNR gain. Finally, some numerical experiment results are provided to demonstrate the effectiveness of the proposed method.
