摘要：

We have developed an on-line system which automatically identifies ships observed in a rapidly updating sequence of range-Doppler images produced by inverse synthetic aperture radar (ISAR). In the system, in order to cope with the invariable noise due to the physics of imaging, we propose to employ a multiframe image processing algorithm which stably extracts profiling as a basic feature reflecting the entire characteristics of a target. For ship identification, representing the extracted profiles as high,dimensional vectors, we adapt the vector analysis using the recently proposed Constrained Mutual Subspace Method (CMSM). The system currently works on an ordinary PC at 5 [frames/sec] and achieves feasible performance of identification. The system is verified using simulated data.
