Design and Realization of the Kind of Step Frequency and Pulse Doppler Complex Processing

In this paper, a kind of step frequency and pulse Doppler complex signal processing system is introducde. Firstly the technologies of step frequency signal processing and pulse Doppler processing are analyzed in detail. The ground clutter characteristic of sky-ground radar and the method of targets detection in clutter are given.Then the mode switch technology between step frequency and pulse Doppler is introduced.Lastly the method of the system's realization and the experiment result are given.The signal processing system is real-time and efficient,and flexible in mode switch.
