With the development of modern equipment technology,the situation of electromagnetic interference in the battlefield becomes more and more severe.In order to keep pace with the times,adapt to the complex environment of modern battlefield,modern radar equipment must be in the original performance,and effectively improve the ability of anti interference,the theory into practice,in order to meet the needs of real-time battlefield.Anti-jamming capability is one of the main signs of measuring radar performance,and it is also an important consideration for the whole system design.Radar interference is generally not a single interference,but a variety of interference composed of integrated interference.This paper focuses on the analysis of positive interference,lists a variety of different types of interference signals.Radar anti-interference must also be used with a variety of anti-jamming measures of integrated anti-jamming technology.In this way,the single equipment has more comprehensive anti-interference ability,so that our products can meet the needs of the times and the battlefield.In this paper,the application and implementation of a variety of anti-jamming technology are studied by using the engineering practice as the main research method in a remote three coordinate radar.From the point of view of engineering practice,this paper introduces several kinds of anti jamming technologies.Firstly,this paper introduces the basic principle of the three phased array radar,the basic composition of the system and its anti-jamming performance.This paper introduces the realization of the technologies of large dynamic range receiver,digital pulse compression,auxiliary antenna and so on.The anti-jamming technology of antenna system is deeply analyzed and studied.Based on the superheterodyne,a variety of anti-jamming techniques have been implemented in the receiving subsystem.Through the digital pulse compression system and digital signal processing system,we can further improve the anti-jamming ability of the radar.According to the technical requirements of the anti-jamming measures,the hardware of each subsystem is improved,or some hardware is added based on the original hardware.In the process of the realization of the anti-jamming technology,the optimization of each subsystem from the perspective of the whole machine,and coordinate the integration of the various subsystems.Some measures for enhancing anti-jamming capability of phased array radar are achieved.We show the best performance of each subsystem of radar.This paper analyzes the effect of some anti-jamming methods.In this paper,we show the real target captured by phased array radar with some anti-jamming methods.Finally,the results show that the anti-jamming method used in this paper has achieved good results,so that the anti-jamming performance of the radar has been improved.
