Book Description
Experiments with a CW, random-noise, X-band, radar ranging system are presented, following the technique proposed and used by G.L. Poirier. The correlation signal-processing method differs from that of other noise radars in that no delay lines are required. The signal-processing technique also decorrelates clutter and other interference, including the transmitted signals of other radar systems identical except for their statistically independent noise sources. An application to small-vessel navigation systems is proposed. Other applications in communications and jamming systems are considered. The experiments verify a ranging accuracy of 1.45 meters at a range of 154 meters. The range capability extends from a minimum of 30 meters to the radar horizon at 19,000 meters in the system constructed. The minimum range and accuracy capabilities exceed those of existing pulsed radars installed in small craft. Possible solid-state implementations using currently available devices are outlined. Proposals for future experiments are made, including shortening of minimum range by increasing transmitted bandwidth, and increasing accuracy by refinement of the laboratory model. (Author).

Book Description
One of the leading causes of automobile accidents is the slow reaction of the driver while responding to a hazardous situation. State-of-the-art wireless electronics can automate several driving functions, leading to significant reduction in human error and improvement in vehicle safety. With continuous transistor scaling, silicon fabrication technology now has the potential to substantially reduce the cost of automotive radar sensors. This book bridges an existing gap between information available on dependable system/architecture design and circuit design. It provides the background of the field and detailed description of recent research and development of silicon-based radar sensors. System-level requirements and circuit topologies for radar transceivers are described in detail. Holistic approaches towards designing radar sensors are validated with several examples of highly-integrated radar ICs in silicon technologies. Circuit techniques to design millimeter-wave circuits in silicon technologies are discussed in depth.
