An Overview of Radar Signal Processing

Radar signal processing lies at the heart of modern sensing and surveillance systems, enabling the detection, tracking, and classification of objects across diverse environments. This talk introduces the core concepts and techniques that underpin radar operation, with a focus on the basics engineers need to understand how these systems detect, locate, and track objects.

Topics will include waveform generation, pulse compression, matched filtering, Doppler processing, and clutter mitigation. Designed for engineers new to radar or seeking a refresher, the session emphasizes intuitive explanations, signal processing aspects, and system-level insights. By the end, attendees will have a solid grasp of the radar signal chain and the essential tools used to extract meaningful information from reflected signals.

Signal Processing in FMCW Radars

FMCW radars are widely used in short range applications such as autonomous vehicles, heartbeat monitoring, vibration measurement in residential and industrial products, drones ranging and intrusion detection. Building the main concepts from the ground up, I will describe in detail FMCW waveform design, FFT processing and the utility of radar date cube that covers all three dimensions, namely range, Doppler and angle. The talk will conclude with practical tips for designing an FMCW radar system.

Beamforming in 5G Cellular Systems: A Tutorial

Cellular networks have to minimize the interference among network users in addition to maximizing their individual data rates. From this perspective, beamforming is the core technology behind the design of the 5G physical layer. In this tutorial, we start from the basic signals and build the fundamental ideas on which physical and virtual beamforming methodologies are based. We will explore how its integration with massive MIMO leads to a simple yet efficient system. No prior DSP knowledge is required to understand the concepts.

Timing Synchronization in Software Defined Radios (SDR) (2020)

A Software Defined Radio (SDR) merges the two fields of digital communication and digital signal processing into an efficient implementation of transmitters and receivers. One outcome of this combination is an interesting perspective on how timing synchronization is performed in digital communication receivers. This session will explain the timing synchronization problem in both time and frequency domains and then discuss in detail a timing locked loop consisting of timing error detectors, loop filter, interpolation and interpolation control. Insights into the relation of timing synchronization with general receiver design will also be presented.
