Design and implementation of real-time simulation system for airborne radar warning

The simulation of airborne radar warning system is to establish their mathematical models, mixed radar signal models and electromagnetic environment. Radar signals can be sorted out though unmixing the mixed radar signal, so that the function of the radar warning system is realized. The modeling method of the airborne radar warning simulation system is proposed, and the simulation system is realized by SystemVue. Through comparing the relationship between the server and the user in the concept of transparence computing, the data transmission mode is changed in this simulation system, and the property of real-time can be guaranteed. In the simulation experiment, the performance of the radar warning simulation system is tested under the different clutter environment. The airborne radar warning simulation system has certain practical application value, because it not only provides a platform for verification of signal sorting algorithms, but also provides the simulation data for the field experiment.
