Radar imaging of ocean-going ships is a function of both SAR and ISAR imaging techniques. Both the radar and the target are moving so the range-Doppler image formation is not due to either a SAR or ISAR imaging mechanism acting alone, but to contributions from both. In this paper we analysis the motions of radar and the ship based on target image projection plane, and present a method to estimate the relative motion between the radar and the ship by Doppler extension of the sub-images. Images of good quality...

Radar imaging of ocean-going ships is a function of both SAR and ISAR imaging techniques. Both the radar and the target are moving so the range-Doppler image formation is not due to either a SAR or ISAR imaging mechanism acting alone, but to contributions from both. In this paper we analysis the motions of radar and the ship based on target image projection plane, and present a method to estimate the relative motion between the radar and the ship by Doppler extension of the sub-images. Images of good quality are required to be from radar data corresponding to the time intervals of smooth change of the Doppler extension. Simulation results are presented which verify this analysis.

运动机载雷达对海面运动舰船目标成像时,由于相对运动的复杂性,直接成像难以达到理想效果。因此必须事先估计两者相对运动变化,对数据段有选择地成像。本文基于图像投影平面原理,分析了机载雷达和舰船目标各自的运动特点,提出了采用子图像多普勒展宽估计雷达与目标相对运动的变化过程,并以此为依据,合理选择观测数据段成像,从而降低了成像难度,提高了成像质量。

We can get much useful information by remote sensing sensor. Wake disturbances contain information about the generating vessels speed, course, length. Space based sensor system could provide naval force with an enhanced capability for surveillance of ship traffic in open ocean areas if the information content of signatures associated with the hydrodynamic wake of a moving ship can be exploited. In this paper, the detection of wakes obtained form satellite images using synthetic aperture radar techniques is discussed. First we analyze the patterns of ship wake in SAR images. Then it is concluded that the problem can be considered a detecting line problem, and we describe the theory and the characteristics of Radon Transform briefly. Finally, we apply Radon Transform to detect narrow V ship wake from some ERS\|1 SAR images. The results show that the algorithm is effective.
