The strapdown guidance technology, which can improve the system reliability and reduce cost efficiently, has been paid great attention and developed quickly. However, the detecting information of strapdown seeker can't be used to proportional navigation directly because it is coupled with missile attitude, so the method of Line-of-Sight (LOS) rate extraction for strapdown seeker is investigated. Background...
In order to produce the motorized spindle unit with high quality and performance and further improve its level of design and produce, a comprehensive performance test system for high-speed motorized spindle is built successfully, it can analyze the load characteristics, temperature rise, vibration, noise, accuracy and rigidity of high-speed motorized spindle unit in different working conditions. Experiments...
This paper presents a compact model for guard rings in lightly doped CMOS substrates featuring a P-well layer. Simple expressions for the impedances in the model are derived based on a conformal mapping approach. The model can be used to predict the noise suppression performance of guard rings in terms of S-parameters, which is useful for substrate noise mitigation in mixed-signal...
Partial occlusion is a difficult problem in computer vision since whether the object is changed or occluded is ambiguous, especially when distinguishing it only from the object boundary. In this paper, we proposed a novel idea to solve this problem by taking shape matching as a morphing processing. A mass-spring model is constructed from the point set which is sampled from a template (or reference)...
Radar target automatic recognition is a comprehension problem. We have researched the practical radar data and concluded some valuable viewpoint. With it we put forward a whole scheme to achieve radar automatic target recognition. First the OS CAFR and binary accumulation algorithm is taken to accurately detect target. Here we lower self-adapt threshold to get more targets which maybe be false target...
The interacting multiple model (IMM) algorithm is mostly applied to state estimation of system whose characteristic changes by time. Itpsilas especially fit for the track of maneuvering object. By using the estimation of parameter in object movement, this paper presents variable structure control, based on IMM of servo system tracked by radar. The algorithm filters the controlled input signals, to...
