| This thesis discusses the key technique of the Pulsed Doppler (PD) radar signal processing, especially on Range ambiguity resolution ,the properties of ground clutters and the algorithms of ground clutters elimination. This thesis introduce the properties of sea clutters, sea clutters elimination, development direction and anti-interference.Firstly, we introduce the development of the Pulsed Doppler radar and the basic structure of PD radar signal processing system and their function of each subsystem.Secondly, we discuss the range ambiguity resolution of Pulsed Doppler radar. In a Pulsed Doppler radar .ambiguity can occur in range or velocity .We introduce several way of range ambiguity resolution and contrast them.Thirdly, we study the clutters of the Pulsed Doppler radar and the clutters elimination algorithms. We analyse statistics properties of ground clutters and study AR model of correlated clutters power spectral density. We introduce several typical clutters elimination algorithms and contrast them. We eliminate clutters using LMS algorithms. This thesis introduce the properties of sea clutters, sea clutters elimination, development direction.Finally, we study the anti-interference performance.We analyse the radar performance of confront electrical spy, anti-interference and confront deceive.We study several technique of anti-interference. |
