Functional Modeling And Simulation Of Airborne Array Radar System

Because the successful application of active phased array radar APG-77 on the F-22 fighter aircraft, the computer simulation technology which is applied in real-time radar algorithms and system becomes increasingly mature. Through testing the radar functional module and system, the functional airborne phased radar simulation system which is based on Visual Studio 2010 platform has been designed in this paper, and the realization of Reds fight Blues real-time simulation has been completed, which is a guiding significance to research on strategy and method of operation.In this paper, firstly the principle when the difference of pulse repetition frequency selection, targets will fall into different clutter regions was dicussed. Combining with the different three ways of working mode, for instance track and search mode, track while search mode and sudden detection mode, the overall scheme of Red against Blue and the overall composition of the single airborne radar simulation system in a functional level was proposesd in this dissertation, and then the input and output interfaces of the radar system was defined. Then the principle of a plurality of modules were introduced, mainly including a phased array antenna module, a coordinate transformation module, a environment echo power generation module, a target detection module, a data processing module, a resource scheduling module, a anti stealth module, a anti-jamming module, etc. The initialization parameters were based on the XML technology, and then the control interface and display interface were illustatec in this article. And then the single well-built radar system was expanded into four red aircrafts against four blue aircrafts. The paper completed verifying eight targets situation display and B shows. At the same time, the efficiency of single radar simulation system also was verified. First of all, the correctness of the antenna pattern and the results of the wave arrange and the attenuation coefficients of meteorological clutter in different weather conditions were tested. Later, the difference of filtering data that the airborne active phased array radar searches and tracks a number of targets in three work models were compared. In detecting single target circumstances, the accuracy of filtering data, the range changes of taking measures of the anti-stealth measures, the range error of adding one type of jam were analyseed. The simulation results verify the effectiveness and correctness of the airborne radar system.Based on the software of standardized components, the modular, standardized, high cohesion and low coupling thoughts were used to establish the system, which is not only perfects the radar models base, but also can set up a new system quickly and easily, to strengthen the function of the module transplantation.
