A general evaluation.system for optimal selection performance of radar clutter model

Journal of Systems Engineering and Electronics 2023年第6期34卷 1520-1525页

作者： YANG Wei ZHANG Liang YANG Liru ZHANG Wenpeng SHEN Qinmu College of Electronic Science and Technology National University of Defense TechnologyChangsha 410073China

The optimal selection of radar clutter model is the premise of target detection,tracking,recognition,and cognitive waveform design in clutter *** characterization models are usually derived by mathematical simplification or empirical data ***,the lack of standard model labels is a challenge in the optimal selection *** solve this problem,a general three-level evaluation.system for the model selection performance is proposed,including model selection accuracy index based on simulation data,fit goodness indexs based on the optimally selected model,and evaluation.index based on the supporting performance to its *** three-level evaluation.system can more comprehensively and accurately describe the selection performance of the radar clutter model in different ways,and can be popularized and applied to the evaluation.of other similar characterization model selection.

关键词： radar clutter clutter characterization model model selection performance evaluation.

Research on Airborne Terrain Matching System

引用

Journal of Energy and Power Engineering 2014年第3期8卷 578-584页

作者： Yachong Zhang Yazhou Yue Science and Technology on Aircraft Control Laboratory Flight Automatic Control Research Institute Xi 'an 710065 China

In view of the airborne application characteristics such as flexible flight, large error of altimeter, large initial error of inertial navigation system, etc., a new terrain matching system architecture which is suitable for airborne application is presented. The key techniques in terrain matching system realizing process including system workflow, terrain matching algorithm and selection criterion of matching region are expatiated. The experimental results prove the rationality and feasibility of the proposed solution.

关键词： Terrain aided navigation acquisition probability applicability performance evaluation.
