This paper mainly deals with the problem of detecting a target against spherically invariant random vector (SIRV) clutter in the presence of steering vector mismatches. Assuming that the mismatch of the steering vector satisfies the conic constraint, the generalized likelihood ratio test (GLRT) is devised, and the geometry description is proposed for the derived solution. Additionally, the fully adaptive GLRT is derived by replacing the exact covariance with fixed point estimate (FPE). Finally, several numerical results are provided and discussed.

Self-localization in unknown environment is one of the most fundamental tasks for mobile robot. In this paper, a novel localization method for mobile robot working in unknown environment is presented by using scale-invariant natural landmarks. Firstly, corner detector was used to detect the interesting points and get the natural land marks, and then a 3D map of the environment was built. Lastly, the mobile robot localized itself by matching the landmarks in the current frame to a database map. Experiments show that global localization and navigation can be achieved in real time.
The cable-driven mechanism is usually used in robotic systems for the efficient transmission of forces or torques from actuators to the end-effector. However, the control design is challenging for these systems due to...

A magneto-optic imaging system is presented in this paper to detect invisible and buried subsurface flaws in metallic structural, which can be used to monitor structural health. The resulting power of the MO imaging system is mainly given by the parameters of the MO thin films, the magnetic excitation device and image processing algorithms. In this paper, the choice of the MO thin films, the design of the magnetic excitation device and the development of the image processing approaches are introduced in detail. Experimental tests have been done and the method presented is evaluated by the experimental results.

This essay presents the DSP + FPGA structure based high-performance image processing system. It aims at solving the overtime-processing problem brought by the increasing complexity of images through the cache-structured image-processing driver. This system allows frame-dropping whenever the processing of images runs overtime and achieves one frame. The system simulation result shows in this way the diver achieves higher efficiency than traditional ping-pong mode when dealing with the overtime-processing of images.
