This book presents the theory, analysis and design of microwave stepped-frequency radar sensors. Stepped-frequency radar sensors are attractive for various sensing applications that require fine resolution. The book consists of five chapters. The first chapter describes the fundamentals of radar sensors including applications followed by a review of ultra-wideband pulsed, frequency-modulated continuous-wave (FMCW), and stepped-frequency radar sensors. The second chapter discusses a general analysis of radar sensors including wave propagation in media and scattering on targets, as well as the radar equation. The third chapter addresses the analysis of stepped-frequency radar sensors including their principles and design parameters. Chapter 4 presents the development of two stepped-frequency radar sensors at microwave and millimeter-wave frequencies based on microwave integrated circuits (MICs), microwave monolithic integrated circuits (MMICs) and printed-circuit antennas, and discusses their signal processing. Chapter 5 provides the electrical characterization and test results of the developed microwave and millimeter-wave stepped-frequency radar sensors. Finally, a summary and conclusion is provided.

Abstract: The design and development of two different, small, low-cost, low-power radar sensors are presented in this thesis. A stepped frequency continuous wave (SFCW) radar and a first-in-first-out (FIFO) noise radar are designed and implemented to detect and track moving ground vehicles through weedy foliage. This is done with both the target and radar close to the ground. In addition, the operating principles of both radar systems are presented from a mathematical point of view. The target tracking is performed both in range and azimuth. A monopulse technique is used to track targets in azimuth. Each of these radar sensors is implemented using state-of-the-art, surface mount, and commercial-off-the-shelf (COTS) components. The operating band of the SFCW radar is chosen as 3.0 - 3.6 GHz. The design procedure of a new concept radar, called FIFO noise radar is presented in detail. The FIFO noise radar is operated at a center frequency of 3.3 GHz with a bandwidth of 100 MHz. The performance characteristics of both radar sensors are presented. It is shown that the SFCW radar is a feasible radar sensor for tracking moving ground targets in both range and azimuth, because of its high amplitude sensitivity and stability. The range tracking capabilities of the FIFO noise radar sensor are also presented.

This book provides readers with a solid understanding of the capabilities and limitations of the techniques used for buried object detection. Presenting theory along with applications and the existing technology, it covers the most recent developments in hardware and software technologies of sensor systems with a focus on primary sensors such as Ground Penetrating Radar (GPR) and auxiliary sensors such as Nuclear Quadruple Resonance (NQR). It is essential reading for students, practitioners, specialists, and academicians involved in the design and implementation of buried object detection sensors.

A step frequency ground penetrating radar (SF GPR) system was characterized and evaluated to determine whether it can be operated safely in a proposed configuration that may include frequency notching in specific frequency bands. This emission testing was conducted with possible notching configurations turned on and then turned off to allow for both scenarios to be evaluated. Testing work focused on emissions characterization measurements suitable for computer analysis of potential interference with relevant systems. After initial testing was completed, needs for follow-up testing were defined. This follow-up testing was completed, and results are included in this report.
