Underwater Imaging Using a 1 × 16 CMUT Linear Array
A 1 × 16 capacitive micro-machined ultrasonic transducer linear array was designed, fabricated, and tested for underwater imaging in the low frequency range. The linear array was fabricated using Si-SOI bonding techniques. Underwater transmission performance was tested in a water tank, and the array has a resonant frequency of 700 kHz, with pressure amplitude 182 dB (μPa·m/V) at 1 m. The -3 dB ...
متن کاملSimulator Development For Multiple Unmanned Underwater Vessels
This paper is about the development of a system that will simulate the operation of multiple Unmanned Underwater Vessels (UUV’s). The simulator is being designed to support the research efforts of the Position, Navigation and Timing (PNT) team of the Naval Research Laboratory (NRL), located at Stennis Space Center. In this paper, we will discuss the functionality and architecture of a simulator...
متن کاملThe Sonar Simulator for Underwater Navigation
Position of surface objects can be fixed in many ways. The most popular radionavigational systems, including satellite systems, make possible obtaining nearly continuous and very precise ship’s position. However, under the water application of radionavigational systems is impossible. Underwater navigation requires other tools and solutions then these encountered in surface and air navigation. I...
متن کاملCell Morphing: From Array Programs to Array-Free Horn Clauses
Automatically verifying safety properties of programs is hard. Many approaches exist for verifying programs operating on Boolean and integer values (e.g. abstract interpretation, counterexampleguided abstraction refinement using interpolants), but transposing them to array properties has been fraught with difficulties. Our work addresses that issue with a powerful and flexible abstraction that ...
متن کاملFocal-Plane Array Architectures: Horn Clusters vs. Phased-Array Techniques
The science goals of the SKA specify a field of view which is far greater than what current radio telescopes provide. Two possible feed architectures for reflector antennas are clusters of horns or phased-array feeds. This memo compares these two alternatives and finds that the beams produced by horn clusters fall short of fully sampling the sky and require interleaved pointings, whereas phased...
