Phased Array Radar System Simulation And Interference

Phased array radar is the product of radar technology developed to a certain stage, it's also one of the important directions of the radar technology development. Compared with conventional radar, it has many technical advantages and broad prospect of application. However, it is limited to obtain so many important technical parameters during its procedures of the research and testing because of its complex equipment and high prices, while phased array radar simulation system solves the problem to some extent, because of its very strong flexibility, repeatability, economy and other advantages.This paper mainly studies the phased-array radar system simulation and several deceptions jamming.1. It researches phased array antenna direction figure, and compares it with the simplified model. At the same time, it makes use of the simplified directed graph, generating amplitude and poor space and difference beam direction figure function.2. It analyzes the phased array radar signal processing model. It mainly introduces the pulse compression, constant false-alarm processing and angle measurement modules; before introducing the pulse compression, it analyzes the characteristics of the linear frequency modulation signal. Meanwhile, it does relevant simulation.3. It studies and analyzes the phased-array radar data processing model. It focuses on analyzing and studying the target track processing by using congruence algorithm solution distance and velocity ambiguity. It includes track starting and ending, point mark - correlation and target tracking.4. It researches and analyzes the four deceive type jamming. By comparing the theoretical analysis with the simulation results, it testes and verified the correctness of the contrast. At the same time, in the course of analysis, it gives the problems that should be paid attention to in the implementation of interference to provide a reference for the implementation of jamming.5. The phased array radar simulation system has been designed and accomplished, and in this paper it introduces the composition of the design and implementation of phased array radar simulation system and function. It also carried on the corresponding simulation test and analysis to provide a basic experimental platform for the related research. Because its receiving and other modules are similar to the modules of the traditional radar, therefore, this paper did not do any analysis, it's directly simulated on the system.The realization of the design of this system mainly uses Matlab software to design and realize the function modeling and verification, and on this software platform it builds out phased-array radar system simulation platform.
