In this paper, we have proposed a M&S tool for analyzing detection coverage and target localization in bistatic radar system. The detection coverage determined by radar parameters is meaningful when it satisfies the clear line-of-sight condition. We improved the method to find the minimum altitudes of transmitter and receiver for meeting the condition by considering three-dimensional coverage. Its computational burden is not problematic because the calculation is for maximizing the performance of the radar and does not demand a real-time operation. In addition, target localization on three-dimensional earth model based on the information of the height, longitude, and latitude is proposed instead of the previous unpractical calculation on two-dimensional bistatic plane. Its precalculated result can reduce its computation burden and it is suitable for real-time estimation of target location.

The RUAV is connected to various sensors to receive and save attitude and position data with the flight control computer as the center and simultaneously controls the servo motor depending on the mission by automatic control command. Complex inner tasks satisfy assigned deadline, interact each other and operate system. If quality of these control software have problem, it can have fatal effects. To secure the reliability of control software, analysis, design and verification steps should be performed in advance. This paper proposes analysis, design and verification method about RUAV system using the RTP of UML. Based on system’s requirements analysis, we design software using general resource model, concurrency model and schedulability model profiles of RTP from various points of views. Verify the designed software using the statechart and the rate monotonic scheduling theory.
