Course Description
This course is designed for entry-level engineers, technical managers, or students with a basic electrical engineering background seeking to understand how multiple antenna elements collaborate to steer a beam electronically without physical movement. We begin with an introduction to phased array systems through the lens of ray-optics principles, followed by a comparative analysis of the benefits and trade-offs between dish antennas and various phased array designs. We will then explore array fundamentals, specifically focusing on how element and array factors contribute to the overall antenna pattern. This section delves into beam steering approaches across different geometric configurations and addresses critical design consequences such as sidelobes, grating lobes, beam squint, and inter-element mutual coupling.
The course then examines modern design approaches by highlighting the distinctions between active and passive arrays, alongside the advantages and complexities of analog, digital, hybrid, and optimal beamforming techniques. Moving into practical applications, the session covers instrumentation and implementation details specifically for telemetry, emphasizing the role of modeling and simulation during the design phase. To ensure a comprehensive understanding. Calibration and testing techniques for verifying the underlying assumptions of the design are explored. The program concludes with a challenging real-world case study and solution, followed by a summary and a Q&A session.
About Anand Kelkar
Anand Kelkar, Chief Technology Officer at Creative Digital Systems Integration (CDSI) in Simi Valley, CA.
Mr. Kelkar received his BEE from The Cooper Union for the Advancement of Science and Art, New York and an MSEE in Radar & Communication Sciences from University of Southern CA, Los Angeles. Since 1979 Mr. Kelkar has adventured with signal processing in the Electromagnetic spectrum, initially with Radar applications and later with Telemetry. In 2006 he founded CDSI with his long-time associates. CDSI has focused on the development of multi-beam phased array antennas which are comprised of antenna ‘tiles’. As the Chief Technology officer at CDSI he is responsible for steering the product portfolio which also includes Radar and Telemetry Environment Simulator systems. Mr. Kelkar holds multiple patents in the fields of Radar Transmitters, Environment Simulation, Digital Beamforming Radar techniques and Space-Time signal processing techniques for optimal beamforming. He has co-authored and presented papers in various technical forums and symposia.
