Research on application of Keystone transform in radar

摘要：

Keystone transform for wideband LFM signal after dechirping is presented in this paper,which can correct range migration and improve the speed of signal processing. The affection of Keystone transform on echoes of ballistic targets with micro-motion and extracting micro-motion information is studied.Simulation experiments are carried out,whose results prove that the algorithm proposed above is valid.Simultaneously,we can draw the conclusion that in order to extract micro-motion or micro-Doppler information Keystone transform should not be applied.
