We propose an instance segmentation model, named CoMask, that effectively alleviates the scale variation issue and addresses the precise localization. Specifically, we develop a multi-scale feature extraction module (MSFEM) to exploit multi-scale spatial cues. Besides, the channel attention mechanism is also adopted to further enhance the discriminating ability. Equipped with MSFEMs, multi-scale a...Show More
This paper establishes the flight control system model using the Harmony-SE method, and realizes simulation of the aeronautical weapon trajectory from the launching point to the target point. The characteristic of flight control system of aeronautical weapon is that all functions revolved around the calculation and iteration of system state.

Bus-integrated computers have a wide range of applications in the aerospace field. But few of them use Saber for simulation modeling of bus-integrated computers. Using Saber modeling, it is possible to target device level, subsystem level and supersystem simulation, which facilitates faster development iterations and shorter development time. To address this issue, this paper first uses Saber to m...Show More
Aiming at the problems of long development cycle, poor reusability and portability in avionics software development, this paper proposes a development process based on MBSE(Model-based systems engineering) and FACE(future airborne capability environment) architecture. At the same time, the differences between SysML model and FACE data model lead to the incoherence of development process. Therefore...Show More
