PAB1: Phased Array Bootcamp

Presentation Abstract
The Boot camp runs ½ day (4 hours) including 20-minute break. Four modules will be presented. The broad theme of the bootcamp is to educate, the high frequency (RF,MW and mm wave) engineers, the processing in the digital world where the analog RF waveforms from array antenna and electronics are available in digitized form. Popular techniques for beam shaping, beam spoiling, null steering, beam optimization, interference mitigation will be explained, targeting applications like massive MIMO, Reflective intelligent surfaces (RIS), direction of arrival estimation etc. The goal is not to delve deep into mathematics, but to provide an intuitive understanding of the techniques. Even though the algorithms are analytically sound, they often lose their efficacy due to the impairments in the electronics and antenna array. Hence treatment of all important RF impairments, how they can be captured accurately, and modeled accurately, will be discussed. The impact of RF impairments on the algorithms will be presented as well. Calibration techniques will be discussed to show recovery of the desired functionality by increasing the efficacy of the processing algorithms. The expected audience will be a mix of experienced phased array designers and engineers new to this field.
