A New Method for Imaging Avian Based on Frequency-stepped Chirp Signal

摘要：

It is very important for the security and development of humans aviation as well as the development of avian ecology and the prevention from avian influenza that avian could be imaged by ISAR (Inverse Synthesis Aperture Radar) with frequency-stepped chirp high-resolution radar. In the paper, a new imaging method for avian targets is proposed, by which ISAR image quality can be improved obviously. In the method, the different parts of birds gliding spectrogram are connected and the minimum waveform entropy criterion is employed for phase compensation. The feasibility and effectiveness of the methods are proved by simulation results.
