Multifunction Phased Array Radar Resource Management: Real-Time Scheduling Algorithm
In this paper a real-time task model of multifunction phased array radars is built, and a novel scheduling algorithm is proposed. This algorithm takes the priority of task’s function mode and deadline into account synthetically, and can adapt well to different load conditions. Based on the task model, the algorithm can achieve the variety of scheduler’s time load in a real-time fashion and adju...
متن کاملSynthetic phased-array terahertz imaging.
We demonstrate terahertz (THz) imaging with enhanced spatial resolution by a synthetic phased array. A single mirror is used to separately form two different coherent, diffraction-limited THz images of the same point source. The two images are combined to yield a 4x resolution-enhanced image of the source in one dimension.
متن کاملFinite Difference Time Domain Simulation of Ultrasonic Phased Array Imaging
This paper reports the simulation of phased array ultrasonic wave propagation using Finite Difference Time Domain (FDTD) method to image crack like defects in Aluminum Blocks and Stainless Steel elbow sections. Inclined crack like defects have been considered for the simulation. Experiments were also performed on an Aluminum block with inclined embedded cracks various sizes in order to validate...
متن کاملThree-dimensional Real-time Synthetic Aperture Imaging Using a Rotating Phased Array Transducer
Current 3D real-time imaging is done either with sparse 2D arrays, or with mechanically moved phased arrays. The former results in a poor resolution and contrast due to a limited amount of elements. The latter has the disadvantage of low frame rates due to the sequential acquisition of the volume line-by-line and plane-by-plane. This paper describes an approach which combines mechanically moved...
متن کاملPreliminary work of real-time ultrasound imaging system for 2-D array transducer.
Ultrasound (US) has emerged as a non-invasive imaging modality that can provide anatomical structure information in real time. To enable the experimental analysis of new 2-D array ultrasound beamforming methods, a pre-beamformed parallel raw data acquisition system was developed for 3-D data capture of 2D array transducer. The transducer interconnection adopted the row-column addressing (RCA) s...
