Research Of Satellite-ground Bistatic/Multistatic Radar Network Detection Simulating Technique

Satellite-ground bistatic/multistatic radar network detection, is a kind of bistatic/multistaticradar network detection mode, that transimitting by space-borne radar and ground radar,while receiving by ground radar. With combined the advantages from the stereoscopicspace, and the ability to coordinate the various radars working organically in the net, thismode could give full play of the overall performance of the radar system, and has obviousadvantages over single radars. As a result, it becomes one of the hotspots in radar area inrecent years.Because of the complexity and huge cost of radar network system, it is necessary thatcomputer simulation technology has used in the research and analysis of the systemperformance. Therefore, the research of the Simulation System of satellite-groundbistatic/multistatic radar network detection has theoretical significance and practical value.The main work and results are as follows:1. The simulation framework of the simulation system of satellite-groundbistatic/multistatic radar network detection is Studied, and simulation objects andsimulation process has modeled, in which based on the target scattering model hastheoretical analysis the superiority of satellite-ground bistatic/multistatic radar networkdetection.2. Detection simulation method of satellite-ground bistatic/multistatic radar networkdetection is studied. We established a signal model, and specifically addressed the modelsor methods in each of the major aspects of detection simulation. Then we took a specificsimulation example to demonstrate the detective effectiveness of the system. The resultsshow that satellite-ground bistatic/multistatic radar network detection has obviousadvantages over ground radar network detection and single radar, which is consistent withthe theoretical analysis.3. False alarm simulation method of satellite-ground bistatic/multistatic radar networkdetection is studied. We proposed a network detection false alarm simulation method, thatbased on the bistatic radar ellipsoidal coordinates model, which can simulate the numberand the spatial locations of false alarms of network radars. Simulation results show theeffectiveness of this method. This job has applicated a national patent.4. The simulation software of satellite-ground bistatic/multistatic radar network detection isdeveloped. With its modular design and flexible parameters configuration, the software can help designers to carry out the system demonstration and distribution solution selecting ofradar network.
