A cooperative maneuver decision method for multiple unmanned aerial vehicles is proposed to address the close-range air combat problem in this article. As the perfect information of adversary is impossible to obtain, a state predicted influence diagram model is established to solve the problem of the maneuver decision in the close-range air combat. The elements are analyzed comprehensively based on...
Multi-target threat assessment is a considerable issue of air combat tactical decision. As the conventional approaches are deficient and imperfect in the procedure of determining the attribute weights and result display of the threats, a novel threat assessment method based on Prioritized Visibility Graph Ordered Weighted Averaging (PVGOWA) operator is proposed. In this work, the relative threat function...
To assimilate satellite-based passive microwave observation over heavy clouds and precipitation into numerical weather prediction (NWP) systems and thus to improve the performance of it has become an intensely studied topic. These attempts rely on the development of a radiative transfer (RT) model that accounts for particle scattering and accurately simulates the observation process at an acceptable...
Extreme weather observations with temporal resolution of ∼15–30 minutes and spatial resolution of ∼15–30 km are required to improve forecasting of mesoscale severe weather events. Due to recent advances in microwave receiver and filter technology, the fleet concept of ∼30–40 CubeSat nanosatellites has been identified as an alternative but cost effective means to meet the requirements. OSSEs of CubeSat...
The numerical simulations of imaging technology for analysis of geostationary multispectral passive microwave observation is described. This paper compares the abilities of three candidate passive microwave sensors to image the upwelling atmospheric brightness temperature. Presented are scattering-based simulations of a land falling hurricane that illustrate the imaging capabilities of a filled-aperture...
This article uses the graphics designer and the code editor of GL Studio combined with VC++6.0 to simulate the instruments which is based on a certain type aeroboat. This paper introduces the GL Studio software, its main function and its application in aeroboat simulation. This simulation result can real-timely shows the parameters (speed, altimeter and electrical quantity) of the aeroboat, and it...
An improved FCM (fuzzy C-means) algorithm is applied to classify the multi-target in the air combat, and divides them into several colonies averagely according to the simulation in different targets compared to traditional FCM algorithm. Meanwhile, this method reduces the computational complexity, and raises the operating speed by considering multi-target as a whole. Finally, multi-target colonies...
