Typical System Of Radar Jamming Simulation Study

Radar interference is a new way for war which has developed in the World War II. It has an important value in military field. This thesis systematically studied the interference technique of three kinds typical system radar. The main parts as follows.First, this paper research and analyze the feature of signal of pulse Doppler radar, and the mathematic model of radar is constructed. The several interference methods that narrow-band suppressing interference, range deception interference and velocity deception interference are discussed. And interference ability is evaluated and simulated. Second, research and analyze the feature of signal of pulse compression radar, and discuss the principle and characteristic of pulse compression technique, that are linear frequency modulation and phase coding. The above two mathematic model is constructed, and shift-frequency noise is imposed on the models, and anti-nose ability is evaluated and simulated. Third, research and analyze the feature of signal of Frequency Agile radar, and the mathematic model of the radar is constructed. The best interference methods to Frequency Agile radar is achieved, and interference ability is evaluated.The research result of this thesis can be applied in future electric war system on large size, and medium size worship that will improve the fight ability of navy electric war equipment.
