A simple model is proposed for the radar returns from a slow-moving target with wake on sea surface, based measurements of submarine mast. This used to investigate effect broad Doppler spectrum detection in clutter. It shown how relative magnitudes and its affect performance. Non-coherent coherent detectors are compared it that some circumstance non-coherent may give better performance, depende...

This paper deals with the design of a moving sliding surface in a variable structure plant for a second order system. The chattering phenomena is also dealt with during the switching process for an unstable sliding surface condition. The simulation examples considered in this paper shows the effectiveness of the sliding mode control method used for the design of the moving sliding surfaces. A s...

As a category of challenging flow problems, flows with moving boundaries and interfaces, includes fluid–particle, fluid–object and fluid–structure interactions; free-surface and two-fluid flows; and flows with moving mechanical components. To address the challenges involved in computation of this category of problems, we developed a number of interface-tracking and interface-capturing technique...

We have developed a motion analysis method that combines the wavelet transform with the ow surface image technique. In dynamic navigation environments, whenever objects move, the projections of the objects onto the image plane also move. These projections build over time spatiotemporal surfaces of their movement and volumes created by the surfaces. This paper presents a new method for the inter...
