Modeling And Simulation Of Passive Radar System

As the growing capacity requirement of the four-anti radar system in modern war, the passive radar has been studied and applied widely due to the advantages of fine concealment and long-distance detection. Modeling, simulatiing and analyzing the performance of passive radar system mode by simulation method has become an important research filed now.This dissertation employs a combination of Simulink and Visual C++ platform to establish passive radar model libraries and simulation system with the model libraries. The formation of the pulse description word is the basis of passive radar signal processing. This dissertation first introduces parameter measurement model which can measure the time domain, frequency domain and spatial domain parameter, gives an intra-pulse modulation mode and extract intra-pulse modulation parameter. Moreover, radar signal sorting is a key technology of electronic countermeasures. This dissertation gives a detailed description of the main sorting method which is based on parameter PRT, and establishes the signal sorting model. In order to determine the interested emitter's position. Finally, the passive radar system is constructed and simulated. Simulation results validate the correctness of the above system.
