High-speed and high-maneuvering target detection method based on TRT and special GRFT

Abstract

For high-speed and high-maneuvering target detection, a detection method based on TRT and special GRFT is proposed in this paper. Firstly, the range migration and Doppler migration caused by target velocity and jerk are corrected by TRT. Secondly, estimation of target acceleration can be realized by special GRFT. Then, the estimated acceleration is used to construct a compensation function to correct the range migration and Doppler migration caused by acceleration. Finally, we can achieve coherent accumulation simulation results demonstrate the effectiveness of the proposed method.
