Design And Implementation

Aiming at those problems faced by armored force which carried out real communication countermeasure training under complex electromagnetic environment, a simulation system was developed. Based on the analysis about threats faced by armored communication and the process of armored communication countermeasure, the system function and the federation member structure were designed, and the system was realized in the end by the distributed simulation technology of HLA. This system showed good performance of scalability and reusability, so it is suitable for the training of armored force.

It is a challenging task to control an unmanned aerial vehicle (UAV) in complex electromagnetic environment. The effective anti-jamming simulation is an economical and efficient method to test and verify the control effect of an UAV. This paper introduces a method to construct an anti-jamming simulation system for an UAV firstly. Then, the procedure to validate the anti-jamming performance of an UAV is proposed. In the following, the evaluation methods in signal level and function level are described in detail for the model validation. The model effectiveness is evaluated both qualitatively and quantitatively. The simulation test results agree with the flight results very well.

Speed Up

This paper builds an infrared scene of sphere target based on JAMSE, which provides EO/IR environment and is suite to build infrared imaging simulation system of engineering and engagement-level. In addition, to speed up this infrared imaging simulation, we analyzed the process of external rendering mode, which is applied in JMAES EO/IR environment, and found the external rendering image compounding is a highly independently process, which is suite to parallel computing. After testing on NVIDIA TESLA C2075 GPU with CUDA, and comparing the performance with the corresponding sequentialprocess on CPU, we got a satisfied result. This process obtains a speed up of over 10.
