Design of an Aperture Phased Array System for the SKA
نویسندگان
چکیده
Aperture phased arrays operating up to 1 GHz are highly flexible collector systems, uniquely capable of performing an HI survey of a billion galaxies and observations of the Epoch of Reionisation, two of the Key Science Programmes for the Square Kilometer Array, SKA. Such high performance arrays are only becoming feasible in the timescales of the SKA due to technological advances in array design, low noise amplifier implementations, and increased processing and communications speed. In this paper we discuss the scientific benefits of an aperture phased array system operating from 70 MHz to 1,000 MHz, using a mixture of sparse and dense arrays and show their implementation as part of the SKA is achievable and highly desirable.

The EMBRACE is denoted as the Electronic Multi-Beam Radio Astronomy ConcEpt which is planned as two aperture arrays with multiple independent Field of View (FoV) capabilities. A 300 square metre aperture array will be based in Westerbork close to the Westerbork Synthesis array and a second 100 square metre aperture array will be based in Nancay. The main objectives of EMBRACE are to demonstrate...
متن کاملPulsar searches and timing with the SKA
The Square Kilometre Array (SKA) is a planned multi purpose radio telescope with a collecting area approaching 1 million square metres. One of the key science objectives of the SKA is to provide exquisite strongfield tests of gravitational physics by finding and timing pulsars in extreme binary systems such as a pulsar-black hole binary. To find out how three preliminary SKA configurations will...

Executive Summary In this report we show that a distributed cooling system delivering liquid coolant to all the front-end LNAs of an SKA mid-frequency aperture array station is not only practicable but can also be implemented in an economically beneficial way. The aperture array configuration can be adjusted to either deliver an overall cost saving or conversely produce a sensitivity improvemen...
متن کاملPhased array antenna using MEMS phase shifter
This article presents a phased array antenna employing MEMS phase shifter. The proposed phased array antenna consists of eight square patch antennas operating at 10.4 GHz with a bandwidth of 400 MHz. Feed line for each patch passes through a MEMS phase shifter realized by a series of bridges above the transmission line. The distance between the bridge and the transmission line underneath it is ...
متن کاملPhased array ultrasonic imaging using an improved beamforming based total focusing method for non destructive test
One of the novel ultrasonic phased array based scanning methods for ultrasonic imaging in non-destructive test is total focusing method (TFM). This method employs maximum available information of the phased array elements and leads to an improved defect detection accuracy compared to conventional scanning methods. Despite its high detection accuracy, TFM behaves weak in distinguishing the real ...
