Application of Adaptive Kernel Time-Frequency Distribution in ISAR Imaging with Complex Motion Target

摘要：

The ISAR image will be blurred using the traditional range-Doppler algorithm for imaging maneuvering targets.Time frequency analysis is an effective method for solving this problem.On the basis of analyzing the radar echos Doppler frequency timevarying characteristic with complex maneuvering in detail,a new adaptive kernel time frequency distribution (AKTFD) which is suitable for complex maneuvering targets ISAR imaging is introduced.The new algorithm for estimation the kernel functions parameters is also proposed in this paper.Simulation result based on simulated data and real data shows the validity of proposed algorithm.
