Small And Short-range Radar Systems Gregory L. Charvat Pdf (2025-2026)

In the modern era of wireless technology, radar is often viewed as a "black box" technology—esoteric, expensive, and reserved solely for military defense contractors or high-level aerospace engineers. However, over the last decade, a paradigm shift has occurred. Radar has shrunk from massive, power-hungry installations into compact, efficient devices capable of being integrated into cars, drones, and even smart home devices.

The simplest project in the book involves continuous-wave Doppler radar. This is the technology used by police to catch speeding cars. Charvat simplifies the circuitry to its bare essentials, allowing the builder to detect the speed of a moving object (like a person walking or a car driving by) by measuring the frequency shift of the returned signal. small and short-range radar systems gregory l. charvat pdf

This is the heart of short-range radar. FMCW allows you to measure distance (time-of-flight) without using a super-fast clock. Charvat explains the "beat frequency" concept so clearly that you can code it in Python within an hour. He includes design examples for automotive radar (24 GHz and 77 GHz). In the modern era of wireless technology, radar

Gregory L. Charvat recognized this gap. During his tenure at the Massachusetts Institute of Technology (MIT) Lincoln Laboratory and as a visiting lecturer, he pioneered a philosophy of "pedagogical radar." He argued that to truly understand radar, one must build it. This philosophy culminated in the creation of the "Coffee Can Radar," a project that demonstrated how a functioning radar system could be built for under $200 using simple parts like tin cans and off-the-shelf RF components.
