Research On Fast Synthesizing The Deception Jamming Based On DJS

With the rapid development of radar technology,the performance and ECCM capability of radar have been greatly improved. The effect of conventional jamming techniques reduced seriously in recent years. To counter these new radar systems,especially to counter masses of radars at the same time,using the DJS system is essential. The DJS system could produce the best jamming signal against the new radar systems especially large numbers of radars and threatening signals more effectively.This paper studies the popular radar jamming technology such as DRFM and DJS and analyzes the principle of DJS from the point of electronic countermeasure. Based on the discussion of DJS and LFM signal,this paper presents some simulation experiments on the deception jamming of pulse compression radar and realizes time delay jamming and frequency shift jamming and also analyzes the jamming effect. This paper analyzes the relationship between the measurement error and the jamming effect by simulation. The simulation results show that when the measurement error within a certain range, using the DJS system could make deception jamming effectively on PC radar.
