基于分段伪Keystone变换的快速旋转目标检测
Fast Rotating Target Detection Based on the Segmental Pseudo Keystone Transform
摘要
Abstract
It is a challenge to detect or recognize targets with fast complex motion for high range resolution radar,by reason of migration through resolution cells (MTRC) during the observing time. Aiming at solving the problem of MTRC for rotating targets , this paper proposes a new method named Segmental Pseudo Keystone Transform ( SPKT), to correct the MTRC. Observed data is divided into pieces obeying the rules firstly. Each piece of data is processed by the SPKT to realize MTRC correction. And then, data processed is put together to level the HRRP in the whole observing time. Based on which, coherent integration is carried out during the accumulation time.The fast realization is achieved by employing the Discrete Match Fourier Transform (DMFT) .Computer simulations demonstrate the validity of this algorithm.关键词
