Research On Data Processing And Simulation Of Radar Network

With the progress of electronic countermeasures (ECM) technology, the threaten which single radar faced is growing increasingly. The radar network can fully use resource and advantage of single radar, and synthesize different system, different band and different polarization, the campaign ability of radar network increases hugely. This dissertation simulates the key technique of radar network. An improved association algorithm based on velocity information is introduced firstly, then a radar network data processing model is built, at last, the multiple false target jamming countermeasures performance is analyzed and some suggestions are given about radar network.This thesis comprises five main chapters, and content will be summarized later one by one.The background and significance of this research is briefly specified in Chapter 1, the status of radar network data processing are summed up in detail, and the key problem and researching thoughts are shortly put forward for the later interpretation.Track association algorithm is discussed roundly in Chapter 2. At the outset, this chapter summarizes the basic knowledge of track association. Then, it brings in an improved association algorithm based on velocity information. At last, the new algorithm is compared with traditional algorithms. The validity of the proposed algorithm is indicated by simulation results.The modeling and simulation of radar network data processing is thoroughly analyzed in Chapter 3. This chapter divides objects into ballistic object and aerodynamics object, and tracking filter is set up. Then, the simulation model of track association algorithm is built, which includes time alignment, spatial registration and association. At last, the model of track fusion is built. The basic structure of the radar network data processing is constituted.The multiple false target jamming countermeasures ability is analyzed in chapter 4. The theory of multiple false target jamming is introduced firstly. Then, this chapter expounds the theory of the multiple false target jamming countermeasures ability. At last, two different multiple false target jamming scenes are proposed, the performance of the multiple false target jamming are analyzed and some suggestions about the radar network design scheme are given.In conclusion, Chapter 5 summarizes the whole dissertation particularly in the main work and innovation facets, and then offers several suggestions for the succeeding research.
