| Stand-off Jamming(SOJ) plays an important role in electronic warfare systems. Simulating and evaluating SOJ is very important to its application and effectiveness in combat.First, we briefly introduce the working principles and characteristics of ground early warning radar and Stand-off Jamming. Also, the advantages and disadvantages of existing simulation methods are discussed. Moreover, we propose a new simulation method based on vectorization parameter model. A simulation system is then designed with Visual C++6.0,MATLAB and OpenGL, which is made up of simulation models for each combat unit. Finally, we thoroughly analyze interfering performances in the case of one ground early warning radar to one or more Stand-off Jamming planes and anti-interference performances of various signal processing algorithms in radar receivers.Simple Factory Pattern is used in this simulation system in order to separate the display and calculation program part. These two parts communicate with each other just through input interface and output interface, which makes the system easy to maintain and further extend. The display part indicates the system's parameter settings and checks, pattern generation and signal display. The calculation part is encapsulated with Dynamic Link Library(DLL), including video signal calculation and effective jamming area calculation. The simulation system can display radar scanning results and effective jamming area results. It can also display these results after receiver signal processing, such as MTI/MTD, pulse compression, coherent/incoherent integration and CFAR. |
