title = "Intra-pulse velocity compensation for HRWS-SAR with high squint looking",
abstract = "HRWS-SAR steers the antenna to increase the synthetic aperture which causes the radar changes beam squint angle gradually. The squint angle increases with the demanding of the resolution and swath width. With the squint increasing, the relative velocity between radar and lighting swath may reach several km/s. It causes the intra-pulse modulation on the echo. The traditional pulse compressing under the stop-go-stop assumption has bad performance including resolution decrease and PSLR increase. The paper established the echo model. The chirp rate is slightly changed because of the relative velocity. And velocity compensation method is put forward. The experiment results show that the pulse is well compressed. The PSLR and the resolution are restored to normal level.",
