Phased 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 ...

Quantization Analysis for Reconfigurable Phased Array Beamforming

In reconfigurable phased array radars beamforming is performed in the digital domain. Digital implementation can be carried out using finite precision and infinite precision representation of the phased array signal. We consider finite precision representation, since it takes considerably less implementation resources compared with the infinite case. In this paper we analyze quantization effect...

Photonic Integrated Circuits for Phased-array Beamforming

Photonic integration is very promising to bring down volume and weight of phased-array beamforming networks. In addition, photonics allows for increased functionality for widebandwidth systems. In this paper we demonstrate the feasibility of phase and amplitude control of a 16-element phased-array antenna with a single InP integrated circuit. The concept and design of an optical phase locked lo...
